While her 'Glee' character Quinn has been rejected by ex-boyfriends Finn, Puck and Sam on the hit show, it looks like Agron's own love life isn't fairing so well either. Us Weekly reports that Dianna, 25, and Stan, 28, ended their relationship as a result of Dianna's uncontrollable jealousy. A source described the 'Glee' star as "super-jealous," revealing, "She was always worried that he was cheating on her while he was away filming, but he never would!"
Another report suggests it was the long-distance dating that made the relationship impossible to maintain, with Dianna filming in L.A. and Stan in N.Y.C. A New York Post Page Six source reports, "Long distance wasn't working. Dianna's coming to New York for Christmas with her mom, so they might rekindle the flame."
The couple first stepped out together in late May, just months after Agron split with her ex Alex Pettyfer, who she costarred with in the flick, 'I Am Number Four.'
