Britney Spears's romance with Jason Trawick turns violent?

According to Star Magazine, Britney Spears's romance with Jason Trawick has turned violent!

In the Dec. 13 issue, on sale today, Britney's former husband Jason Alexander tells Star that the pop princess confided to him that Trawick beat her -- on multiple occasions.

"Britney is in an abusive relationship," he says. "She told me her life had turned into a nightmare."

Spears recently confided that Trawick "hit her so hard it gave her a black eye," Alexander says.

Alexander says he's telling this story because he's "really concerned" for Britney who he feels is "telling me these secrets as a way of getting out of this."

Britney Spears' rep just gave TMZ a statement, which calls the audio recording posting online "so obviously fake as to be laughable."

The statement goes on: "Suffice it to say, Jason Trawick has never laid a hand on Britney."
