Leighton Meester: Killer Body, Killer Movie

Leighton Meester shows off her legs-for-days at the premiere of her new movie, Killer Movie, during the 2008 Tribeca Film Festival on Thursday in New York City.

The Gossip Girl star wore Pencey‘s Beefy Cotton Cumberbund Dress in Bosky Green.

The horror comedy Leighton stars in is about a reality television shoot that goes terrifyingly awry. Its camera crew becomes stranded in a remote Northern town where a killer is on the loose, stalking cast and crew one by one. Sounds entralling.

Earlier in the day, the 22-year-old cutie was seen shooting scenes in NYC for her CW drama, Gossip Girl. Be sure to check out all of her fun and flirty costumes below!
