Coachella is going down this weekend in California's Palm Desert, and we're hoping that music-loving celebs come out in force this year just as they did in 2010! Beyoncé Knowles, who announced she's performing at Glastonbury, has been out on the West Coast and may swing by again, while a break from touring for Katy Perry means she could see her "ET" collaborator, Kanye West, on stage Sunday. Melancholia costars Alexander Skarsgard and Kirsten Dunst both hung out at the shows last Spring — there even may be a reprisal of an Alexander Skarsgard shirtless sighting! Ladies' man John Mayer is no stranger to an outdoor festival, while Kristen Stewart might attend for the second year in a row to celebrate her 21st birthday. Follow Buzz on Twitter for updates, and tell us — which star would you like to catch a show with this weekend?
