Kevin Federline spends Britney Spears's cash

Kevin Federline is spending major cash decorating a top of the line nursery in his rented 3.2-million-dollar bachelor pad for the two sons he shares with estranged wife Britney Spears reports Star Magazine.

Kevin Federline dropped 14-grand at the Los Angeles baby boutique Petit Tresor on Thursday, July 12, a source tells Star.

"Federline was in the store for close to an hour," the source goes on to say, "and was carefully selecting the right theme for each child."

"You could tell he really put his heart and soul into this," the source adds, "and was precise in what he envisioned when describing each of his sons' personalities."
