Jay-Z and Beyoncé were in a Coachella state of mind this weekend, as the couple headed to the desert for Jay's Friday performance at the fest. Not only was B there to support her hubby, she also joined him onstage to sing "Forever Young" later in his set (see video above).
The VIP crowd Friday night included Katy Perry, Paris Hilton, Rachel Bilson and cute couple Kate Bosworth and Alexander Skarsgård, who later got into a scuffle with photogs. Read on for more of what the stars were doing onstage and off...
After his show, Jay-Z got his party on at a private house in Palm Springs, where he and Beyoncé arrived around 1:45 a.m. Belvedere was flowing at the small soiree with only 50 other guests, including Solange Knowles.
On Saturday, the couple hit the fest again and were spotted watching U.K. indie rock band The XX among all the regular concertgoers. Also checking out last night's lineup was Whitney Port, engaging in PDA with her new boyfriend from The Buried Life, while Kristin Cavallari hung out by the bar with Hayden Panettiere in VIP.
After the shows Saturday night, celebs headed to 944 and Armani Exchange's neon carnival, where Josh Hartnett rode a mechanical bull and Kellan Lutz hit the dance floor. Newly single Paris Hilton danced up a storm with her sister and told E! that this was her "best Coachella ever," while David Hasselhoff, who was in attendance with his daughter, snapped photos with surprised fans. Lindsay Lohan opted to hit up the Adidas party instead.
Stars stayed out even after the official parties shut down. Paris invited people to her rented house at 4 a.m. to continue the fun, while Rumer Willis retired to her RV with friends.
