Coachella Day One: Paris Hilton leads the charge as celebs come out in fashionable force for first day of festival

Forget Glastonbury, Coachella is now the ultimate festival to be seen at.

And the US celebrities were out in force yesterday to prove their music and fashion credentials on the first day of the California extravaganza.

Paris and Nicky Hilton celebrated 'sibling day' at the site, donning white lace outfits in attempt to channel the original bohemian vibe of the, now huge, festival.

Paris bizarely chose to finish her outfit with a pair of cat ears.

And not to be outdone, Kylie and Kendall Jenner proved they were making the most of sibling day in their best festival outfits.

Kylie made sure all eyes were well on truly on her by debuting her bright green hair to the throngs of revellers.

Fergie from the Black Eyed Peas got her boho-chic to look a bit more natural-rocking out in a festival failsafe of denim shorts and tee.

She even added a tassled waist-coat for extra authenticness.

Katy Perry chose a more off-the-wall vibe, rocking a patterned playsuit with neon accessories as she hung out with Mia Moretti at a private pool party away from mere mortal festival dwellers.

Azealia Banks looked fantastic in tiny shorts and a midriff-baring white blouse as she performed her set to a raptuous crowd.

The rapper's performance was met with positive reactions from critics as she held her own against some big names in the first days' line up.

Rock legends ACDC headlined along with Interpol and Steely Dan.

But the US celebs were also joined by some of our very own showbiz royalty with Kimberley Garner being spotted enjoying the California sun in all-white.

Brooklyn Beckham was also seen with a harem of women as he navigated the different stages that make-up the gigantic party in the desert.
