When it comes to celebrating his 24th year on earth, one night was not enough for The Hills' BRODY JENNER. After an all-night party in Miami two weeks ago, Jenner threw another birthday bash at Pure in Las Vegas Aug. 18. He and fellow castmates LAUREN CONRAD and AUDRINA PATRIDGE sipped champagne and partied with the Las Vegas Pussycat Dolls before ever-present MTV cameras. Which means in a future Hills episode, you'll see: "Brody and Lauren spent a lot of time whispering in each other's ears," says an observer of the former flames. Also making a cameo appearance: Jenner pal LEONARDO DICAPRIO, who later joined the festivities at an afterparty in the cast's Palms Hotel suite.
