Adam Brody and Leighton Meester
Despite Brody’s fizzled-through romance with Rachel Bilson in 2003, the actor eventually found love with the “Gossip Girl” star and fellow teen drama alum. The pair met on the set of “The Oranges” in 2011 and wed three years later in 2014. They welcomed their first child, Arlo, in 2015, and have probably been living in bliss ever since. But, obvi, that hasn’t stopped fans from writing Seth Cohen/Blair Waldorf fanfic.
