It looks like it's splitsville for one of "Gossip Girl's" real life couples.
According to US Weekly, Penn Badgley and Blake Lively have ended their 3-year relationship. The couple apparently broke up back in September.
"They're professionals," an insider tells Us Weekly. "They're still good friends and hang out on the set."
The source says that the duo - who met as preteen actors in L.A. - "kept this news to themselves for a while."
The couple was always very private, and the announcement of their split even came as a shock to those close to the pair.
