The sizzling star turnout at this weekend’s annual Coachella Music Festival rivaled the desert heat! Kate Bosworth (in a Suno dress and Joie sandals), Rachel Bilson (in a Brigid Catiis shirt, Paige Denim shorts, Joie sandals and Ray Bans) and Beyonce were among the stylish set who flocked to the Indio Valley, California polo fields to see an amazing lineup of artists, including Jay-Z, Muse and the Gorillaz. Jay-Z surprised Friday night’s audience by performing “Forever Young” with wife Beyonce, who rocked the stage in cut-off True Religion jean shorts and a Wildfox Couture off-the-shoulder tee.  When they weren’t braving the heat to see their favorite bands and DJs, stars such as Bilson, Camilla Belle and Kristen Stewart sought shade at various parties such as Lacoste’s poolside bash in Indio. What artists brought Bilson out to Coachella? “I was really excited to see Jay-Z. Once he came out, it was just amazing,” she told us. “It was so crazy. We almost left but decided to stay. I’m glad I saw [Beyonce perform].” When it came to stylishly surviving the desert festival, the actress recommended one of her favorite trends this season. “I’m really loving backpacks,” she said. “They make things so much easier!” Click on to see more stylish stars at Coachella.
