GOSSIP GIRL star Leighton Meester has reportedly split from her boyfriend Sebastian Stan.
The actress/singer began dating Stan after he appeared on her hit TV series in 2008 but she's said to be single again after calling off their romance.
A source tells OK! magazine, "Leighton called it quits because she doesn’t know how to be in a relationship and doesn’t really like them. Sebastian is heartbroken by Leighton’s decision to end the relationship.”
