Although he tried to blend in with the crowd, fans and media in attendance couldn’t help but spot Robert proudly watching his girlfriend on Saturday evening. The Twilight star was dressed down for the occasion, wearing one of his trademark beanie hats with a light grey t-shirt and blue jeans.

R-Patz's pal Katy Perry was also seen enjoying Twigs' set, but the ‘Teenage Dream’ singer was a little easier to spot in her pink and blue crop top and skirt combo. Twigs was making her debut at the California festival, performing in the Gobi tent at 9.35pm.
