It's the music festival that's become synonymous with fashion - and we could see why as Coachella 2011 kicked off this weekend.
Katy Perry had the 70s vibe down as she showed off a cute floral headband teamed with a cream lace belted maxidress, and she was also spotted letting her hair down in 60s-style white sunnies and a red checked cropped top.
Kelly Osbourne posed for pics in her cute 50s-style wrap dress, which she teamed with socks and boyfriend shoes, as well as a fedora and hot pink lips.
Kate Bosworth was also spotted in a cool stars and stripes number, while Transformers star Isabel Lucas rocked that hippy chic too in a dip-dye maxidress and headband.
Stars were treated to sets by Cee Lo Green and Lauryn Hill, while there'll also be performances by Kanye West, Arcade Fire, The Strokes and more.
Other celebs who spotted at the fest included Dita Von Teese, Paul McCartney, Ashley Greene and Paris HIlton.
