Though the former Gossip Girl star hasn't officially announced it yet, judging by these recent photos of her out in Los Angeles, it's pretty safe to say the 29-year-old actress is expecting.

Leighton married the 35-year-old O.C. actor in February 2014. This will be the first child for both of them.
