With Coachella festival being just a stone's throw from Hollywood in the Southern California idyll of Palm Springs, it's unsurprising that it's unfailingly star-filled every year.

Following the announcement of his forthcoming collaboration with H&M, Alexander Wang threw a party attended by Coachella veteran Kate Bosworth as well as fellow regular Katy Perry, Hanne Gaby Odiele and Aluna Francis. 

Poppy Delevigne continued her seemingly never-ending hen night with the stars of her socialite circle, Sienna Miller and Cara Delevigne in tow.
