The New Man of the Spears House

Subtle, but firm.

That's how we'd describe the latest effort of a rebellious Britney Spears to replace husband Kevin Federline. With her marriage reportedly on the rocks, the sexy star has hired a male nanny to help care for their seven-month-old son, Sean Preston. Rumor has it that K-Fed is quite jealous of the new guy in Britney's life.

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

The male nanny -- who some in the press have nicknamed "Manny" -- has been identified not as Red Sox outfielder Manny Ramirez (below), but as a man named either Perry or Henry, according to numerous reports.

He was hired to be a bodyguard for Spears at first, but he's since become the man of the house... a very lucky man of what has to be a very strange house.

In Touch reports that Manny/Perry/Henry has been doing chores that had previously been done by Federline, and has even been spotted buying flowers for Spears.

Wait a second... Federline did chores? Who would have guessed?

To make matters even tougher on poor Kevin, Mrs. Federline is redecorating the house, tossing her husband's beloved black leather furniture in favor of some more feminine tastes.

"She's using pink, cream and apricot silk, lace and feathers," reports an inside source. "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.'"

Whatever it takes to get him out, Britney. Whatever it takes.
