The 27-year-old Gossip Girl actress and 34-year-old O.C. actor have been very quiet about their relationship, and tied the knot in a secret ceremony.
Leighton and Adam co-starred together in the 2011 comedy The Oranges. She’s been previously linked to actors Aaron Himelstein and Sebastian Stan, while Adam has dated screenwriter Lorene Scafaria and co-star Rachel Bilson.
Congrats to the happy couple!
