Another Gossip Girl Couple Donezo?

So maybe Ed Westwick and his girlie are fine, but sources say Leighton Meester and her boyfriend and sometimes fellow Gossip Girl co-star Sebastian Stan are not.

Friends close to the couple say they have split with Leighton breaking things off. Insiders say that she “doesn’t know how to be in a relationship and doesn’t really like them.”

Good girl gone BAD!

And what’s not to like, girl?! He seemed nice enough!

We just can’t figure that one out!
