Justin Timberlake sure knows how to get an A-list crowd on its feet. At the “SexyBack” singer’s House of Blues concert in Hollywood, girlfriend Cameron Diaz sang along to every song and rocked her body on the balcony with two female friends. “She was cheering just like a fan,” says an onlooker. “She was dancing and swaying around.” And she wasn’t the only one.
Ellen DeGeneres and Portia di Rossi grooved hand-in-hand while Tyra Banks screamed “Oh, yeah!” and gyrated to the music. Kate Bosworth also jumped around when Timberlake sang “Last Night” and Jeremy Piven got sweaty dancing to “Señorita.” Also in the house for the show: Paris and Nicky Hilton and Timberlake’s ‘N Sync pal Lance Bass, who made the scene with boyfriend Reichen Lehmkuhl.
Timberlake will be taking his show on the road: He’ll tape the season premiere of DeGeneres’s talk show in New York City’s Central Park on Aug. 28 (the episode airs Sept. 4) and will hit the stage Aug. 31 at MTV’s Video Music Awards, where he’ll perform his hit “SexyBack” live.
Kristen Takes the Bar
Talk about multitasking. Kristen Bell wasn’t just content to hang out at the recent premiere afterparty for her horror film Pulse. The actress decided to mix things up and play bartender for the cast and crew at Hollywood’s L’Scorpion. “The crowd loved it,” says a source, who reported that the Veronica Mars star’s specialty was brewing up a screwdriver. “They were laughing. They even left her tips.” Looks like she has a second career in the making.
