Coachella Valley Music And Arts Festival celebrated its 9th anniversary this year and as usual a whole host of celebrities made the trek out to the desert to enjoy heat and music. Nicole wasn't the only person there with a Madden as a date, Paris and Benji were hand in hand to enjoy the weekend. Sienna Miller and Kelly Osbourne were attached at the hip most of the time while Shia LaBeouf flew solo (actually looking pretty good again). Prince was one of the weekend's most talked about performers but Sean Penn also had his own moment up on stage. He was there to announce and embark on a cross-country trek using a fleet of biodiesel buses. Of course, the festival looks like a blast that resulted in probably more than a few sunburns and probably a few days recuperation for everyone.
