Brody Jenner had a party at Privilege Nightclub in Hollywood to celebrate his 23rd birthday, which you can tell from the people that showed up, was STAR STUDDED! Stavros Niarchos came out of hiding. There was booze there and it was in Hollywood so of course Tara Reid showed up. Jack Osbourne, Kim Kardashian, and a party aint a party until a Hilton appears (even if it was Nicky and she had boyfriend Kevin Connelly in tow). But the real story of the night was not that Jenner showed up with his mom as his date but he left the party at the end of the night, holding hands with Nicole Richie, not Kristin Cavallari! Is Jenner's wallet getting a little thin and think Nicole Richie will be a cheaper date?
