Apparently, if you're Britney Spears, you think that you can have your greasy man-cake and shove it in your estranged ex's face, too.
According to In Touch Weekly, the Britinator dialed up K-Fed's cell to ask how he's doing... and if he has, by any chance, seen any good Britney Spears pictures lately.
Specifically, pictures of her sucking massive amounts of face with new boy toy and quote-unquote music producer J.R. Rotem (below).
Britney proceeded to brag about a sexual escapade she'd just had with J.R. What's more, Britney has reportedly been taunting Kevin Federline about his new and significantly less-impressive financial status.
"It was really bad," says an eyewitness. "[Britney] just started pushing his buttons ... he started screaming at her."
Man. Hopefully Kevin can channel some of his obvious rage when he goes up against John Cena in a WWE Raw title match on New Year's Day.
Otherwise... well, this is the just kind of grating bull$h!t that can make a disturbed guy go O.J. Simpson on his ex-wife. If he did it, of course.
