Jamie Chung warms up in a tan poncho sweater as she arrives at the 7 For All Mankind 10th Anniversary Celebration in Beverly Hills earlier this week.

The 27-year-old Sucker Punch actress was just added to the cast of Hangover 2.

Jamie will star as Ed Helms‘ new fiancee. Hangover 2 reunites the stars from the original — Bradley Cooper, Zach Galifianakis, Ed and Justin Bartha — and transposes them in a misbegotten trip to Thailand.
