"Britney feels outraged and betrayed," confided a close source. "Only three weeks after she gave birth to their new baby, Kevin vamoosed to Vegas with his buddies, who spent hours with young girls in his hotel suite.

"When Kevin returned to their Malibu home, Britney gave him the cold shoulder and then they had a terrible fight. It ended with Kevin staying over at a buddy's house."

In other news, Britney is keen to re-launch her pop career and had hired dancer Matt Felker, who appeared in her Toxic video, to work with her on the promo for her new single.

But Kevin, who met the Toxic singer when he was a dancer on her world tour, was far from happy with his wife's choice and demanded she axed all the male performers because he is worried she will find love with another dancer.

A source told In Touch Weekly magazine: "Kevin insisted that Britney fire Matt and all of the other male dancers she'd hired and replace them with females.

"He is surprisingly insecure and secretly terrified she will leave him if her career takes off again."
