Parties! The style, stars and scoop from Hollywood's hottest events

Though temperatures in the California desert reached well past the 100 degree mark, the Coachella music festival was an oasis for music fans. And though there were plenty of perks for visiting VIPs, Sienna Miller chose to keep it low-key, staking out a patch of grass—accompanied by her parents!—to catch a performance by Hot Chip. During the three-day gathering, the hip crowd watched living legends like Prince take the stage and made sure to take the time to cool off at parties all over Palm Springs.
