Rihanna and Chris Brown sure don’t forget each other’s birthdays, and Rihanna let the Twitter world know it by directly and publicly tweet greeting her infamous ex on his 23rd birthday yesterday.

They’re obviously on really good terms now, especially after collaborating for RiRi‘s controversial “Birthday Cake” remix, but what might Breezy‘s protective and territorial girlfriend–slash Rihanna’s alleged Twitter enemy–Karrueche Tran might think?

RiRi tweeted her former boyfriend with a rather boring greeting:

“Happy Birthday @chrisbrown.”

No Twitter replies from CB or rant tweets from Karrueche at the moment.

Do you think Karrueche will react negatively about Rihanna‘s public greeting to Chris?

Lady Gaga seems to be enjoying her “normal” way of life lately, what with her normal clothes and her unusual media vow of silence, that even she decided to celebrate her birthday without lavish parties or a public bang. Unlike many celebs who would start having their fancy-shmancy party hours before midnight and stretch their celebrations until a whole week, Mother Monster simply started her celebration hours before by going on Twitter and uploading a photo of a rather sad-looking cake.

She tweeted along with the caption:

“This is how it feels turning 26 in three and a half hours. Ha!”

And other than crowning herself with a rhinestone tiara earlier yesterday, Gaga had an exclusive spin class party at Soul Cycle with some of her friends.

A source told Us Weekly:

“She requested [Bruce Springsteen's] ‘Thunder Road’ because it’s one of her favorite songs. Her friends filled the studio, and they had a blast.”

Shockingly, Gaga even opted to stay in with her parents for her birthday dinner instead of painting the town red with multi-colored glitters as we sort of expected she would.

The source shared:

“It was just a small thing with her family. Her mother cooked.”

Although it may just have been a simple case of a superstar wishing to have a relaxing day after being in and out of rehearsals for her “Born This Way” tour, as one of Gaga‘s female friends reveals:

“She’s been ridiculously busy, and has been working herself very, very hard. But everyone had the most amazing time [yesterday]!”

Sounds a little too quiet for a celebrity, but this is tres better than the usual Vegas celebrity party!

Happy birthday, Rob!

Rob has definitely had one hell of a year—the biggest highlight of which was his successful stint on “Dancing With the Stars.” The reality star, who is usually overshadowed by his more successful sisters, won a second place finish on the dance competition show last year, thanks to the patience and guidance of his partner, Cheryl Burke, his “secret weapon” butt, and his vastly improved dance moves.

Pretty impressive for a guy who just sits in the background, don’t you think?

Rob rang in his 25th birthday with Kris, Kim, Kendall and Kylie in Las Vegas, starting off with dinner at Stack Restaurant & Bar, which they followed with a quick visit and photo op at the Kardashian Khaos store at the Mirage Hotel.

Noticeably absent from the festivities were Kourtney and Khloe, who instead greeted the birthday boy via Twitter.

The Kardashian Klan then spent the rest of the night partying at 1Oak Nightclub, where Rob was presented with an extravagant four-tier birthday cake.

And lastly, a funny photo of Kris Jenner wilding out on the dance floor, which Kim aptly caption:

“Mom gone wild”

Who knew Kris was such a party animal?

The newly single and sexy Eva Longoria was in the company of her party gals Victoria Beckham and Kate Beckinsale once again when she rang in her 37th birthday at Cecconi’s in Los Angeles last night. The ”Desperate Housewives” star’s injured foot was obviously all better as she even celebrated with Kevin Connolly, Mario Lopez and his fiancee Courtney Mazza, and several others at Cut last Tueday.

The birthday girl tweeted:

“My house is a flower shop! I’m overwhelmed with happiness today! Thank U everybody!”

Happy birthday, Eva!

Looks like Justin’s “Batmobile” Cadillac CTS-V won’t be leaving the garage for a while, because during the singer’s interview with Ellen DeGeneres, Justin’s manager, Scooter Braun, came out and surprised the newly-minted 18-year-old with a gorgeous set of wheels—a sleek, eco-friendly Fiskar Karma!

Scooter explains the choice:

“We [Scooter and Justin’s mentor, Usher] wanted to make sure you were environmentally friendly and we wanted to make sure, since you love cars, that when you’re on the road, you are always looking environmentally friendly… and we decided to get you a car that would make you stand out a little bit on the road.”

Ellen then piped up:

“A very hard-to-get car!”

Watch the video and see Justin’s reaction to his extremely awesome birthday present:

Typical Paris!

We never expect anything less from the hotel heiress who reportedly won $30K in blackjack at her party in Vegas—which wasn’t really her hitting it quite “big” considering her revenues and her luxurious hours-on-end albeit out-of-control partying history.

The latest star news has it that Paris has now posted photos on her website as proof of how lavish her birthday party was last February 16 where famous guests were handed masks upon arrival, resembling the party in the erotic thriller starring Tom Cruise and Nicole Kidman in 1999.

She tweets the next day:

“Last night was the best birthday party I have ever had in my entire life! The most beautiful amazing extravagant birthday party ever! #YES!”

Yes, she got a cake. And the requisite “30″ candle. But apart from good pals and the crew that traveled with her around the world for her now concluded tour, that was about as much of a celebration for the Brit. Quite a change of pace from the naked impromptu parties she used to hold in the past…but, oh what a difference it’s made for the older…and much happier Britney Spears…

Since Britney‘s been working her behind off for the last six months of her tour, there wasn’t much time to organize a huge blow out for her 30th, but when she wrapped up her last performance in Puerto Rico, she gathered all her closest friends and members of her crew to feast on her five-layer cake…and cupcakes!

Very much the sober Brit to the end.

“Having an amazing time at the end of my tour / belated bday party,”

Britney told her 11.7 million followers on Twitter.

And celebrity news bets she had a really great one, too.

Not leaving BFF and birthday party organizer Kelly Osbourne all alone to defend her from all the crap slung about when her comment on this video below was made public, Miley finally broke her silence in the midst of the media circus that’s stemmed from a joke that was taken out of context…

Speaking through her rep, Miley‘s made it known she hasn’t left her wise-cracking “Hannah Montana” character far behind. And she says her comment was made all in jest to commemorate the first anniversary of her salvia-smoking 18th birthday party last year…the year her friends started calling her “Bob Miley.”

In gratitude to Kelly‘s staunch defense of her character, Miley even tweeted a “cease and desist” order against her pal’s character assassinators:

“Please stop bombarding my friends twitter pages with rude comments. NOTHING gives you the right to threaten people. I love u @MissKellyO :)”

That’s right, Miley haters and detractors…no right at all. Not even if she is a pothead…

Celebrity gossip websites have learned that Miley will be joining the faces of other celebrities like Dianna Agron, Selma Blair, Justin Bieber, Jessica Alba, Gerard Butler, Lily Cole, Brooklyn Decker, Fergie and Scarlett Johannson, who have collaborated to lend their presence to the hard cover coffee table book…

Miley‘s presence in the book is sure to ramp up sales, the money from which will be going towards brain cancer research through two charities called SNOG and HEADRUSH, non-profit charitable organizations that rely mainly on donations for research.

The book will be sold online via thebeautybook.org to benefit more than 17,000 Americans and over 280,000 people worldwide who are diagnosed with brain tumors every year.

A worthwhile cause for a newly-minted 19-year-old, don’t you think?

Celebrity news figures Miley really had a blast at the wild party featuring midgets, clowns, giant stuffed animals, and her closest pals in attendance. Good thing she’s young, and 3 A.M.’s just a drop in the bucket…

“Can’t thank @MissKellyO for the best partyyyy ever! =]]]] i loveeeee you! Let’s just say there was a unicorn in the lobby!”

Miley gushed gratefully on Twitter. And whether she meant it literally or figuratively, it seems Kelly Osbourne really outdid herself on this shindig if mythical creatures, or a simulation thereof, made their way into Miley‘s 19th birthday party.

Kelly earlier promised to make Miley‘s day (and night) so special, it would be “the sickest thing she’s ever seen.” And by “sickest,” Kelly probably meant the “coolest.”

Or, well…”sickest”…if you think about the party’s entertainment cast of characters.

Happy 19th, unicorn girl! Check out photos from Miley‘s 19th birthday party here…

Soulja Boy bought himself a birthday present in the form of a luxurious G5 jet this week. TMZ has learned that the private jet itself only—yes, only—costs $35 million, but the total bill Soulja racked up amounted to $55 million due to the 20 million dollars worth of “enhancements” he added. The rapper reportedly gave the jet a custom paint job, a humongous (and extremely luxurious) bathroom, custom Italian leather seats, special travertine tile flooring, flat screen TVs, four liquor bars, Brazilian hardwood cabinet, and more. Now if only there was a show called ‘Pimp My Jet’…

Oh, and did we mention that he had the outside of the jet painted with his personal logo?

So then, after dropping millions on his super pimped-out ride, Soulja Boy decided to throw more cash around by giving himself a $300,000 birthday party at a Miami club. Celebrities such as Dwight Howard, Bow Wow, and Sean Kingston will be attending the party.

What we’re wondering is, why does he have that much cash to burn? Didn’t he have, like, one hit song? And furthermore, at his age, that’s just not practical! Even super rich celebrities who blow wads of cash all the time wouldn’t drop that much money on one thing.

Any guesses on what Soulja’s going to buy himself on his 22^nd birthday? Maybe his own country?

Hollywood celebrity news learned the two went to Chateau Nightclub at Paris Las Vegas where they ate the customary celebratory birthday cake, and then on to the Sugar Factory American Brasserie for some giant cupcakes.

On the weekend, Kourtney and Scott headed out to Dune in the Hamptons, among other celebrations that had Kourtney tweeting

“Birthday celebration #4 lol. Can’t hang like I used to. #gettingold.”

So what’s next for birthday 29? Elephants on parade?

Clooney and his long-time girlfriend Elisabetta Canalis ate at Mr. Chow in Los Angeles and shared a table with owner Michael Chow. However, that’s were the celebration ended.

“George either has a huge practical joke planned on everyone or he really is have a crisis about turning 50,” said a source close to the actor.“He’s told everyone he doesn’t want to do anything or for them to send gifts. He’s intent on spending it alone because he says he’s too old for birthdays.”

Cheer up, George! You don’t look a day over precious!

Ambrosio, the gorgeous Brazilian supermodel had on a super sexy  low-cut white and blue laced up dress by Emilio Pucci from the Spring 2011 collection.

JWoww is currently on a book tour, promoting her work and signing autographs for the masses that come out to see her. Maybe she decided to keep it a little professional this year!

They have been by her side through thick and thin and call her their ‘family’.

But at Jennifer ‘JWoww’ Farley’s birthday celebrations, her Jersey Shore cast mates were nowhere to be seen.

There was no sign of Snooki, The Situation or any of the gang as the reality star rang in her 25th birthday at a private party in Las Vegas, over the weekend.

Well, 25 is growing up. Is she beyond the hardcore partying like she has been known for or is it just because she might have a behavior clause in her book contract?

The pair even wore his and hers Dolce & Gabbana outfits. Awww! I bet Selena is going to be bombarded with hate mails for a while! Oh well, it will wear off..hopefully.

Happy birthday to you Justin and boy, aren’t you a lucky fellow, so young and so successful and on top of that to be dating such a gorgeous and NICE gal.

Don’t you think Biebs and Selena make a hot couple? Other Bieber news, Biebs is back on the road again as he resumes his My World Tour this week. He heads to the UK for his first UK concert on Friday.

We all know Justin is a die-hard Christian, so this latest stunt follows along nicely with the singer’s good behavior. Indeed, Bieber would like everyone to donate money to a charity aimed to supply clean water in developing nations. He asks that fans donate $17 in celebration of his 17th birthday.

“Together, we’ve made a big difference for many causes. Did you know that about 4,500 kids die each day from waterborne disease? By building clean water projects for villages that need them, we can prevent this! I want to make my birthday matter this year — let’s make it so more kids can grow up to have a 17th birthday like me. Join me to make a change. Even if you don’t have $17 to give I just ask you to go out in your community and try and make a positive difference. Even the smallest act of kindness can go a long way.”

Bravo, Bieb! I actually am very, very impressed. I hope all of you can donate!

Justin who has just won the International Breakthrough Act prize at this week’s BRIT Awards said he only wants Selena Gomez for his birthday! Oops! He didn’t say that I made it up. The constantly buzy teen pop superstar only wants one thing for his birthday is to sleep!

Justin: “What do I most want for my birthday? I want to sleep!”

Let’s hope he gets his beauty sleep! Happy birthday to-be Biebs.

Here are some of Justin’s all time best quotes:

I’m just a regular 16 year old kid. I make good grilled cheese and I like girls

It would be a shame to go out with a hot girl you can’t have a decent conversation with

Uggs. I think they’re ugly. And I think big sunglasses are kind of overrated. I like big sunglasses but not those huge, round ones

I have a house in Stratford and I got a house in Atlanta but I don’t really live anywhere–I live on the road. I’m kind of like living in a suitcase, travelling so much

I don’t think you should have sex with anyone unless you love them

Canada’s the best country in the world. We go to the doctor and we don’t need to worry about paying him, but here, your whole life, you’re broke because of medical bills. My bodyguard’s baby was premature, and now he has to pay for it. In Canada, if your baby’s premature, he stays in the hospital as long as he needs to, and then you go home (Rolling Stone, March 2011 interview on whether he’d like to be an American)

I definitely want to buy my mom a house once I get enough funds. I think that’s definitely something that I want to do. I think that any person, it’s their dream to buy their mother a house

I think she’s cute. And, no, she’s not too old for me. Above 40 is a little too old for me (on Kim Kardashian)

I don’t love money, because once you start loving money, you’ve got a big house and nice cars and just an empty heart, and that’s the truth, I’m not just saying that

The kid rocks and if you don’t agree.. You’re just jealous! Happy birthday Justin!

First of all, yes, it’s completely wasteful and absurd that one would spend that much money on a cake. But this is Paris, afterall. Secondly – how did he, “Paz,” get away with this? After crashing the party and getting wasted, he says he and a friend tricked the security and swiped the uneaten, 70-pound cake! He wrote on his cake:

“I crashed Paris Hilton’s Birthday Party and Accidentally the Whole Cake. I woke up this morning with a birthday cake in my living room,” wrote Paz. “It’s big. It’s red. It says ‘Paris’. And its f***ing delicious.”

No word on what Paris thinks of all this…

How about a 1 in 500 luxury car? Cy supposedly dropped a load on the canary yellow Lexus sportscar for Paris, who seemed to love it. Now Paris has a pink and a yellow car.

The heiress, who turns 30 today, took to her Twitter account to confirm reports that she had been given a Lexus sports car by Cy Waits earlier this week.

She posted a link to one online story that featured the headline, “Paris Hilton’s $1 million birthday supercar”, and explained that just 500 of the luxury cars will be made.

“My boyfriend got me the most incredible birthday gift!” she told her followers. “I love it! He’s so generous and sweet! Amazing!”

 However TMZ says it’s a $375,000 Lexus LFA.. still frekking expensive!

She posted to a link that mentioned the car’s price? Oh boy. Can you imagine spending that much on any kind of vehicle?
