There may have been a Dancing with the Stars elimination – but the pros were still in the mood to party, heading over to Boudoir in L.A. for the Doctrine Denim launch party. Derek Hough hosted the event, and hung close to friends who were visiting from England while Cheryl Burke and Mark Ballas were also in the club. The group stayed well past 11:30, taking tequila shots and going wild. A witness even spied Burke and Ballas sharing a quick smooch.
Kellan Lutz was partying at ESPN the Magazine's body issue bash at Skylight Soho in New York along with Estelle and Adrienne Bailon. The actor mingled with guests and enjoyed Skyy vodka cocktails before taking off.
First Lady Michelle Obama enjoyed a late-night dinner with some female friends at Spiaggia in Chicago. The group kept things light – just ordering two courses and dessert, which they split, along with wine.
After the L.A. premiere of Jackass 3D, the cast and crew celebrated with a raucous bash at the Hollywood Roosevelt Hotel's Tropicana Bar. Johnny Knoxville was super laid-back, hanging at his table with his wife and daughter and snapping photos with fans. Bam Margera was much more social, sipping whiskey on the rocks and introducing his mother around the party. Also there: Ke$ha, who made the rounds in the VIP section.
