Dianna Agron And Sebastian Stan Split

Glee star Dianna Agron, 25, has reportedly split from her boyfriend of less than six months, Gossip Girl actor Sebastian Stan, 28.

The duo has been together since the summer, just a few months after Agron's split from her I Am Number Four costar, Alex Pettyfer. The split between Agron, who works filming Glee in Los Angeles, and Stan, who resides in New York, may have had something to do with that age-old relationship killer — long distance, reports Page Six.

"Long distance wasn't working," a source said about the couple. But there could be hope on the horizon. "Dianna's coming to New York for Christmas with her mom so they might rekindle the flame."

While you're waiting to find out, you can catch Agron in Glee on Tuesday nights at 8:00 p.m. EST.
