Rob Kardashian celebrated his 25th birthday Friday night at 1OAK nightclub in Las Vegas, but it was big sister Kim Kardashian who most club-goers wanted to see.

Wearing a figure-hugging (what else?) sequined cream-colored dress, the former Mrs. Kris Humphries, was the star attraction on the red carpet.

Dancing with the Stars alum Rob was also joined by his mother, Kris Jenner. She was such a party animal, at one point Kim tweeted http://twitter.com/#!/kimkardashian "mom gone wild!"

His teen half-sisters, Kendall and Kylie Jenner were part of the scene for an earlier dinner.

At 3 am, they all the Kardashian-Jenner womenj piled into a private jet and headed back to L.A.
