Hot Hollywood Couple Alert: Adam Brody & Leighton Meester!

Juicier than any bit of goss Gossip Girl could give, our TV worlds have collided: Seth Cohen and Blair Waldorf are... dating?! It's true! Adam Brody and Leighton Meester are Hollywood's hottest new couple! The 33-year-old former O.C. star and the 26-year-old Gossip Girl, who met on the set of their 2011 comedy The Oranges, have been reportedly "hanging out" and are confirmed to be an item. (Gasp! What would Chuck Bass say?!)

"They were always close and friendly," a source told Us Weekly.

You know how it goes... they start off as friends and end up as more! 

While Adam and Leighton have been keeping their relationship on the DL, the adorable new couple have been making their rounds! Earlier this year, they were spotted traveling together to Bangkok, Thailand and were most recently taking in some art at the LA County Museum of Art. 

Ah! It's a match made in TV heaven!

What do you think of Adam and Leighton as a couple? Which TV stars do you hope would secretly get together?
