“Glee” star Dianna Agron and her boyfriend Sebastian Stan broke up, according to the New York Post.

Stan formerly starred in “Gossip Girl” and recently starred in “Captain America: The First Avenger.”

A source told the Post: “Long distance wasn’t working.” Agron has been spending her days in Los Angeles to film episodes of the hit TV show “Glee.” Stan has been traveling and lives in New York.

However, the source said Agron is coming to New York with her mother for Christmas. “They might rekindle the flame,” said the source, leaving open the possibility that the couple may be together after all for the holiday season.

Us Weekly also reported that the two split, citing two sources. A source told Us Weekly: “[Agron] was always worried that he was cheating on her while he was away filming. But he never would.”

The source said Agron was “super jealous” of any woman who appeared close to her boyfriend.

Agron began seeing Stan after a public and acrimonious split with “I am Number Four” costar Alex Pettyfer.
