Chace Crawford and Taylor Momsen are reportedly following hot on the heels of their cast mates with some serious make-out sessions.
The alleged couple - who play characters Nate and Jenny on Gossip Girl - were spotted kissing at a work Christmas party at club Haven in New York.
A spy at Page Six reports that both Chace and Taylor slipped away from the festive fun to engage in some tonsil tennis - yet Chace's rep denies any involvement between the pair.
Last week it emerged that Ed Westwick and Jessica Szohr were spotted locking lips Dallas airport.
And don't forget Gossip Girl's original couple Blake Lively and Penn Badgley.
Sounds like this season's storylines are going to have to keep up with the cast's off-screen antics!
