Leighton Meester was almost unrecognisable as she debuted a raunchy, gothic look on the red carpet in New York last night.

The Gossip Girl starlet braved the chilly weather in a tiny leather mini-dress for an American Eagle Outfitters party, where she also performed her new single.

Her pale skin, smoky eye-make up and blood red lips gave her an undead appearance that suggests she may have gotten carried away by the vampire frenzy surrounding New Moon.

Leighton's racy look comes just days after her GG co-star Blake Lively set tongues wagging with a revealing outfit of her own.
