Celebrities have begun their annual pilgrimage to Indio for the start of music festival season, with Coachella's first weekend of flower-crowns and fringe (and music) kicking off. Last night, Calvin Klein launched their Coachella experience with a desert warehouse party. Cool young things Jaden Smith and Amandla Stenberg, were there, as well as musicians A$AP Rocky and Aluna Francis. Freida Pinto stopped by, and Zoe Kravitz and Twin Shadow got down to music from DJs Alesso, Virgil Abloh, and more. See all the party-goers in the slideshow below.
