Hudgen arrived at Cannes on May 12 and got the party started by attending a special Calvin Klein bash in the evening, where she was seen hanging out with Rosario Dawson. The two stars met at the airport earlier in the day while waiting to be picked up by the organisers.
Immediately after her Cannes visit, Hudgens will head to NYC to start pre-production for her new film Gimme Shelter that is being directed by Ron Krauss. In it, she plays a troubled pregnant teen who runs away from her abusive mother in search of her biological father (Brendan Fraser).
