Tossing her hair, and with a drink grasped tightly in her hand, Vanessa Hudgens is certainly making the most of her time at the Cannes Film Festival. The former Disney star, 22, had a wide smile on her face as she joined an A list crowd at a Calvin Klein bash last night. And in her jaw-dropping emerald green gown, party girl Vanessa certainly held her own amongst the more established stars.

Making a peace sign as she danced to the music, the young actress was joined by a group of friends at the event. After letting her hair down, Vanessa retired to a table where she regained her composure, and retouched her lipgloss. While Vanessa made the most of the dance floor, some of her more high profile fellow guests stuck to the red carpet.
Uma Thurman, 41, wore a flattering floor-length black Calvin Klein gown, which skimmed her modelesque figure. But she certainly didn't share Vanessa' joie de viveur, looking stern as she concentrated on her mobile phone. British model Lara Stone, who does not drink following a spell in rehab, wore an equally stunning gold gown, which clung to her famous figure.
