Kim is, without a doubt, a very beautiful woman, so it’s no surprise that she was also a very adorable kid. Although judging from the too-short fringe and boyish sweater, it seems Kim’s enviable style and fashion sense was cultivated later in life.

But enough about her! This photo is all about Kim’s late father, Robert Kardashian (most known as the lawyer of accused murderer O.J. Simpson), who would have been 68 years old on Wednesday.

Kim posted the photo above on her Twitter account via Instragram, along with the caption:

“Happy Birthday dad! Celebrating with angels”

Hours later, Kim tweeted an old photo of her and her younger sister, Khloe, with their parents, Robert Kardashian and Kris Jenner, during happier times (before they divorced).

Kim wrote:

“Taking it back old school… Me, Mom, Dad & Khloe”

If we weren’t so distracted by Robert Sr.’s too-tight swimming trunks, we would comment more on the fact that mini Kim and mini Khloe look especially adorable in this photo…

And there could honestly be some truth to the claim, especially since Kris Jenner herself admitted that she cheated on her first husband, Robert Kardashian, in her book, “Kris Jenner And All Things Kardashian.”

Robert’s ex-wife, Jan Ashley, and his widow, Ellen Kardashian, have both revealed that the late attorney had doubts about whether or not Khloe was really his daughter. Ashley, who married Robert after his divorce from Kris Jenner, told Star:

“Khloe is not his kid — he told me that after we got married.”

She added:

“He just kind of looked at me and said [it] like it was a matter of fact. He said, ‘Well, you know that Khloe‘s not really a Kardashian, don’t you?’ And I said…’OK,’ and that was it.”

Ellen Kardashian, who married Kardashian for six years before marrying him in 2003, also revealed:

“Khloe brought it up all the time… She looked nothing like the rest. She was tall, had a different shape, light hair, curly hair. Didn’t look anything like the other three children.”

She continued:

“Robert did question the fact that Khloe was his… Any normal man would if they knew their wife [Kris Jenner] had cheated on him.”

So why did Robert never bring it up? Ellen explained:

“He never would have considered a DNA test… He loved her [Khloe] very much.”

Yikes! Could this be true? Khloe does look totally different from her sisters Kim and Kourtney…
