After trying to keep their secret relationship private – an impossibility in Hollywood where even sneezes are carefully documented – Leighton Meester of 'Gossip Girl' fame and Adam Brody, formerly of 'The O.C.,' are most likely dating. It's a match made in teen drama heaven.

So when do they inevitably break up, start dating within their limited social circle of friends and still inexplicably hang out together like nothing happened? More importantly, which season will have a pregnancy scare to boost the ratings?

A source close to the couple (but not so close that the person feels guilty about betraying their confidences) revealed that “they were always close and friendly” and have been “hanging out” for a while.

We believe “hanging out” is code for "boffing" here, but our dirty minds work like that.

Meester and Brody have already been spotted traveling together in Bangkok, and were most recently spotted together by the Twitterverse earlier this month while at the Los Angeles County Museum of Art.

The couple met on the set of their film 'The Oranges,' which revolves around Meester finding herself in a relationship with her much older neighbor, played by Hugh Laurie -- who's Brody's dad in the movie.

Which proves that sometimes Hollywood relationships have more intersecting family trees than an episode of 'Here Comes Honey Boo Boo.'
