After recently denying engagement rumors, "I Am Number Four" co-stars Dianna Agron and Alex Pettyfer have reportedly called it quits.

An unnamed source confirmed the news to Us Weekly, who claims that Agron has moved out of the couple's home. 24-year-old Agron, who stars in "Glee," and 20-year-old Pettyfer have not confirmed the reports.

The two have been rumored to be dating since August and Pettyfer recently praised his co-star during a January appearances on Ellen DeGeneres' talk show. "She's an amazing woman and she's got this old school, classic movie star elegance to her," the actor said.

Earlier this month, Agron took to her blog to express how uncomfortable she felt that her relationship was receiving so much attention from the media.

"I have been getting a lot of questions about things that I don't feel the need to explain or talk about," Agron wrote. "I don't mean it as an insult, I've just never shared private details of my personal life to promote my career or a project that I am working on. To me, it feels like cheating. What is the payoff worth when you haven't taken the fair steps to get there?"

She added, "I am putting my faith in all of those people who know better. Perhaps some of you would rather hear about projects I am working on and so proud to be a part of, not whether or not I'm swapping spit with some guy?"
