“It was the first time I was in serious love with somebody,” Stan, 42, told Variety while reflecting on his time on Gossip Girl.
“Walking around the city, seeing these same buildings and streets — life seemed simpler,” he added.
Stan has often been fairly private about his love life over the years. However, in 2009, he gushed about Meester while speaking with reporters.
“She’s the most interesting, sophisticated, talented and an extremely funny person that I know. She’s really hilarious,” he said at the time, per PEOPLE.
