Vanessa Hudgens - Vanessa Hudgens Reacts To 'White Substance' Allegations

The image quickly began circulating around Twitter and other social networking sites, but the actress' representative was on hand to play down certain allegations, saying that the actress was simply eating "white chocolate". Hudgens was enjoying the Californian festival with her reported boyfriend Josh Hutcherson. The couple soaked up the sunshine and caught some of the festival's 170 musical acts, which included The Strokes, The Black Keys, Arcade Fire, Best Coast, Kanye West and Cee Lo Green. Hudgens and Hutcherson, who star alongside each other in the forthcoming adventure movie 'Journey 2: The Mysterious Island', were also spotted drinking in the Vip tent at the 3-day festival. Other celebrities to be photographed around the site included Kate Bosworth, Lindsay Lohan, Paris Hilton, Joe Jonas and Dita Von Teese.

Vanessa Hudgens is currently starring in Zack Snyder's action-adventure movie 'Sucker Punch', with Abbie Cornish and Emily Browning. The film centres on a young girl who is institutionalized by her abusive stepfather.
