Friday night was a big night in Sin City with Pauly D & Mike "The Situation" beating down the beat at JET Nightclub and LC of The Hills celebrating her 24th birthday at The Bank.
The highlight of Lauren's birthday bash was a gigantic cake in the shape of her second book, "Sweet Little Lies: An LA Candy Novel" which will be out in stores on February 2nd. Rumor has it that LC will be returning to reality TV - perhaps a take on Newlyweds with her long-time beau, Kyle Howard?
While LC partied the night away at The Bank, Pauly D hit the turntables at JET Nightclub - and "The Situation" was showing off his "situation" the entire time. The boys truly got wild and partied "Jersey style."
Saturday night was also a huge night out in Vegas, with Katy Pery as host of a "Waking Up In Vegas" party at HAZE, the newest nightclub to hit the Strip at Aria Resort and Casino at CityCenter. She didn't kiss any girls but she did treat partygoers to an impromptu performance atound 2 a.m. Mickey Rourke and Gabe Saporta (Cobra Starship) were among the many who came out to party with Perry.
