Glee star Dianna Agron has split from Gossip Girl actor Sebastian Stan, according to a report.

The actress began dating Stan in July following her break-up from her I Am Number Four co-star Alex Pettyfer in February.

However, the romance has ground to a halt because Agron is in Los Angeles filming while Stan is based in New York.

A source tells New York Post gossip column Page Six, "Long-distance wasn't working. Dianna's coming to New York for Christmas with her mom, so they might rekindle the flame."
