In a match made in Josh Schwartz's chatty, gorgeous version of heaven, The O.C.'s Adam Brody and Gossip Girl's Leighton Meester are engaged to be married, People confirms. (The story was first in Star.) Seth Cohen and Blair Waldorf co-starred in the 2011 movie The Oranges and have co-starred in our hearts since they reportedly started dating earlier this year. The two also appear together in next year's indie comedy Life Partners, in which Meester plays a lesbian grappling with her BFF's (Gillian Jacobs) new engagement (to Brody). Congratulations, you two.
