Leighton Meester and Adam Brody are engaged, according to sources for both Us Weekly and Wonderwall.

Leighton and Brody started dating in February of 2013, and they met on the set of the 2011 film The Oranges. Interestingly enough, the duo will also be working together again in the upcoming comedy Life Partners. How appropriate!

Adam previously dated director Lorene Scafaria in 2010 and prior to that he was with his OC co-star Rachel Bilson for three years. Leighton's most recent romance was with actor Aaron Himelstein, and before that she was with her Gossip Girl co-star Sebastian Stan for two years.

“Right now their plan is to get married next summer,” a source tells Star Magazine. “They are still deciding if they want a destination wedding or if they’ll marry in Southern California somewhere.”
