Kevin Federline and Victoria Prince at a bowling alley in L.A. (1/8)

Just kidding. They're getting into screaming matches on the phone. And it's all because of K-Fed's new girlfriend, Bitchass Bitch. Actually that's what Britney calls her. Her real name is Victoria Prince. From the Chicago Sun Times:

On Monday, a longtime Spears insider called this column to share tidbits from a nasty phone fight between the entertainer and K-Fed -- mostly focusing on Spears' obsession with Prince, especially when it comes to her children.

Calling the conversation a "total hysterical screaming match," the source claimed Spears told Federline in no uncertain terms she did not want "that [c-word] anywhere near my kids." The witness also reported that Federline apparently went into some detail -- on the other end of the phone line -- telling Spears, "You really don't have much say about that." That was a clear reminder the singer still has limited parental rights when it comes to her sons Sean Preston and Jaden James.

The good news: "Unlike in [other traumas in] the past, Britney didn't go take a pill or a drink, but went downstairs and did some yoga to calm down. ... I think that's a good sign she's growing up and dealing with Kevin's b.s.," added the source. (Source)

You know your life's a mess when the "good news" is that you didn't solve your problems by getting hopped up on drugs or comatose from alcohol. Why Britney is so upset over this chick's influence on her kids and not the hundreds of strippers K-Fed's been with is a mystery. Also a mystery: K-Fed's appeal . . . and the combination on my hot neighbor's underwear drawer.
