Justin Timberlake, having dinner with Jessica Biel and a large group of pals at new Hollywood hot spot Parc after hosting the Nickelodeon Kids' Choice Awards. Later, when the restaurant-lounge revved into club mode, Biel (who was spotted snowboarding with the singer in January) left the restaurant-lounge while Timberlake clapped his hands to the music and shimmied from side to side as he stood atop his banquette.
Mario Lopez, working out on a stationary bike at the Equinox gym in West Hollywood. Last season's Dancing with the Stars runner-up chatted with a pal as he pumped his legs. Meanwhile, on the other side of the gym, actress Emmy Rossum lifted free weights with a girlfriend.
Ashlee Simpson, arriving hand-in-hand with a male companion at L.A.'s Hyde Lounge. The duo – who looked more platonic than romantic – settled into a table near the deejay booth with a group of friends, sipped champagne and got to their feet when a set of Madonna songs began playing. Also making the scene: Robbie Williams, who had a recent stint in rehab, and actress Bai Ling.
