Is K-Fed being replaced?

Britney Spears has hired a male nanny - some have dubbed him a "manny"- to help take care of baby Sean Preston, and the buzz is that her hubby is jealous of the hunky new guy in her life.

The manny, who has been identified in reports as either Perry or Henry, was originally hired as a bodyguard, but lately he’s been taking on the role of “man of the house," according to In Touch magazine, and has been doing chores that had been done by Federline. He was even spotted buying Spears flowers.

"[Federline] doesn't like that this guy is taking care of his baby," an "insider" told the mag. "He feels like Britney is throwing it in his face."

What's more, Spears reportedly is redecorating her house, ditching Federline's beloved black leather furniture in favor of a "1950s boudoir" look she favors. "She's using pink, cream and apricot silk, lace and feathers," reports the insider. "[Kevin] claims that he can't think in the house any more and it's affecting his music. [He] is complaining that the place is 'some high-school chick's bedroom.'"
