Margaret Colin recently caught up with her former Gossip Girl costar Blake Lively, 13 years after the beloved teen drama went off the air. "I ran into Blake on the street, which was hysterical because she's such a big star now. It was a big bear hug on the streets of New York, and she was just having lunch in a cafe," Colin, 67, exclusively told Us Weekly while promoting her Hallmark film Three Wisest Men, which premiered Saturday, November 15. "That was really wild. That was a couple of months ago after I came back from shooting in Vancouver," she explained.
