Ashley Greene was looking pretty zippy on Saturday night at Madame Tussauds Wax Museum in Hollywood.

The Twilight beauty was joined by her castmate Christian Serratos at the Celebrates the Power of Youth party at the museum. Also attending the event sponsored by the volunteer organization Do Something were 90210 starlet Shenae Grimes, Little Miss Sunshine heart-melter Abigail Breslin and noted activist Aubrey O’Day.

Take a look at our pics from the event and let us know in the comments section: What’s the last thing you volunteered for?
