Sounds like Brit Brit has some bite to her.

All these rumors have come out about Britney Spears as a new judge on The X-Factor. Does she keep walking out? Is she feuding with fellow new judge Demi Lovato? Does Simon Cowell regret hiring her? Does she have any actual opinions about the singers or is she just going to love everyone, ala Paula Abdul?

Well, on that last question — a source says yeah, she has opinions and no, she’s not gonna be little Miss Sunshine.

Ryan Seacrest is no stranger to Simon's world, since they used to have a great bromantic tension on American Idol. Ryan's sources said Britney is actually more like Simon than Paula. In fact, the source said Britney is “a pretty harsh judge at times” and even “ruthless.”

According to Ryan, Brit also found her confidence squaring off against fellow judge L.A. Reid when she thought one particular contestant deserved to get through. Guess we'll see how that pans out...
