Kevin Federline is desperate to get his kids

Several ex nannies spilled Britney Spears's dark secrets to Us.

Before Britneyhad Jayden, she asked a nanny to sleep in the same bed with her and Sean.

“She drinks in front of the kids,�? one former staffer says of Spears, 25.

“At first, the drinks would help her loosen up and not be so angry. But she’d inevitably drink too much and be out of it, at which point the nannies would take care of the kids.�?

“She’ll strip down in front of staff, nannies, whomever,�? says one. “She’ll ask, ‘Do I look sexy? Do I look pretty?’ She’s extremely insecure.�?
