Surprise! Adam Brody and Leighton Meester have tied the knot in a secret wedding ceremony.

Brody and Meester, who both rose to fame on teen TV shows created by Josh Schwartz -- him as lovable dork Seth Cohen on 'The O.C'; her as the snooty Blair Waldorf on 'Gossip Girl' -- have made their romance official, sources tell Us Weekly.

The super hush-hush ceremony comes just three months after insiders confirmed the two were engaged. Exactly a year ago, in February 2013, it was revealed that the two were an item. While the notoriously private couple have kept mum on their relationship, pictures speak louder than words: over the weekend, Brody was photographed at LAX wearing a gold band on his left ring finger.

In addition to their off-screen romance, the Brody, 34, and Meester, 27, clearly have chemistry on-screen as well. The two starred together in the 2011 film 'The Oranges,' and will soon reunite on the big screen in the upcoming comedy 'Life Partners.'
