Jamie Chung gets the giggles as she attends the premiere of The Hangover Part II at the Planet Hollywood Resort & Casino on Saturday (May 21) in Las Vegas.

The 28-year-old actress kept it cute in a white dress with fringe booties and 3D Vortex earrings from Stephen Webster as she joked with costars Justin Bartha and Mason Lee at the event.

Next up for Jamie? Premium Rush with Joseph Gordon-Levitt.

Premium Rush follows a bike messenger (Gordon-Levitt) who picks up an envelope that attracts the interest of a dirty cop (Michael Shannon), who pursues the cyclist throughout Manhattan.
