Okay, it's not the Gossip Girl set, but Leighton Meester and Luke Bracey, her Monte Carlo co-star, were spotted smooching on location for the new movie in Monaco.

The cute pair were joined on set by co-stars Selena Gomez and Katie Cassidy, who will be joining the cast of Gossip Girl this fall, as we excitedly reported yesterday.

Leighton and Luke have looked pretty flirty throughout the film shoot - think they’re together now that she and Sebastian Stan called it quits? Doubtful, but who knows!

Leighton locks lips with her hunky co-star.
