Leighton Meester is getting hot and heavy with singer Vanessa Curry in this new music video for The Nomads single "Addicted To Love."

The Gossip Girl starlet is seen in the video kissing Curry! To make it even juicier ... the video was directed by Wilmer Valderrama. Naughty, naughty.

Ms. Meester sure knows how to get our attention!
