Dianna Agron isn't having much luck in love this year.
The Glee actress, 25, is no longer dating Captain America: The First Avenger star Sebastian Stan, 28, two sources confirm to Us Weekly. The couple first began dating in late May, just months after Agron split with her "volatile" ex Alex Pettyfer, her costar in I Am Number Four.
One insider says Agron and Stan broke up because she was "super jealous" of any woman who appeared too close to the former Gossip Girl actor.
According to The New York Post's Page Six, their bicoastal romance became too much for Agron to bear. "Long distance wasn't working," a source told the newspaper. "Dianna's coming to New York for Christmas with her mom, so they might rekindle the flame."
