Kevin FederlineBritney Spears’s choices for a new nanny and interior design have apparently rubbed up husband Kevin Federline the wrong way.

A source has told Us Weekly that Perry Taylor is “more Sean’s bodyguard than a nanny” with a background in the US Navy and working in security, and his mum Caroline has confirmed that the nannying role is new to him: “he’s just beginning to learn about babies.”

According to In Touch magazine, in addition to his bodyguard/nanny responsibilities, Perry has recently been taking on more “man of the house” roles including chores previously carried out by Kevin.

An inside source told the magazine: “[Kevin] doesn’t like that this guy is taking care of his baby. He feels like Britney is throwing it in his face.”

Kevin is also reportedly angered by Britney’s decision to redecorate the house, getting rid of Kevin’s favoured black leather furniture: “She’s using pink, cream and apricot silk, lace and feathers. [He] 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.’”
