Okay guys, this is kinda like a dream come true! We've been obsessed with The O.C back in the days, and lately it's been Gossip Girl - and now we have those two series combined, in a new Hollywood couple! Leighton Meester and Adam Brody have started dating, and we couldn't be more happy about it. "They were always close and friendly", an insider tells. The actors costarred in The Oranges in 2011 and have been hanging out ever since, and now it's gone from business to pleasure. "They have been dating for weeks". Ah, we have a new favorite couple!
