Gossip Girl Leighton Meester looked stunning at premiere of her new movie, Killer Movie, during the 2008 Tribeca Film Festival Thursday in N.Y. City.

Meester and Blake Lively are two of the hottest young stars on TV, and we can't get enough of either! Check out more photos of Leighton here!

Gossip Girl's Leighton Meester shows off her killer good looks.

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

Leighton returns as her Gossip Girl alter ego, Blair Waldorf, Monday at 8 p.m. on The CW. She's the best!
