Britney taunts K-Fed with her sexcapades!

 

While she is having a ball with music producer J.R. Rotem, pop singer Britney Spears is also not missing any opportunity of taunting estranged husband Kevin Federline about her latest fling.

 

Sources say that Britney recently called Kevin to ask him if he'd seen pictures of her kissing Rotem and then bragged about a sexual escapade she'd just had.

 

And as if this wasn't enough, she added salt to his injury by taunting him about the lavish lifestyle he is missing out on since the split.

 

"It was really bad," TMZ.com quoted an eyewitness, as telling In Touch Weekly.

 

"[brit] just started pushing his buttons ... he started screaming at her," the eyewitness added.

 

Meanwhile, Kevin is reportedly gathering evidence of Britney's wild partying to use against her in a custody battle over their sons.

 

 

I'm sure Britney has enough evidence of Kevin being a bad parent. And the partying won't do much against Britney. Can you imagine the kids living with Kevin?? That'd be a disaster, poor Sean and Jayden.
