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…
