Obsessive much?

Apparently, Dianna, who described herself as extremely happy with Stan, was also insanely jealous over any woman who appeared to get too close to the 28-year-old Romanian-born actor…

“She was always worried that he was cheating on her while he was away filming, but he never would!”

a source revealed to US Weekly.

Now why would a nubile 25-year-old blonde cheerleader-type like Dianna Agron be seriously insecure over her scruffy-looking boyfriend?

Celebrity news believes it may have to do with his dark and brooding allure courtesy of his gypsy blood. You think?

“Long distance wasn’t working,”

another source tells the New York Post about the coastal disruption brought about by Dianna‘s L.A. work-base and Stan‘s New York shooting locations.

Dianna’s coming to New York for Christmas with her mom, so they might rekindle the flame.”

The question is, will the utterly cool Sebastian Stan get back together with Dianna Agron now he knows what a jealous girlfriend she is?
