Britney wanted nanny to share bed with her and son!

The nannies that Britney Spears hired to look after her kids may help give her ex hubby Kevin Federline the ammunition he needs against her in the custody battle over their kids.

The nannies are revealing that the troubled pop star not only asked one to share a bed with her and son Sean Preston, but also regularly drinks in front of her young sons.

“She drinks in front of the kids. 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,” Usmagazine.com quoted one staffer, as saying.

Another source reveals that Britney will strip at the drop of a hat.

“She’ll strip down in front of staff, nannies, whomever. She’ll ask, ‘Do I look sexy? Do I look pretty?’ She’s extremely insecure,” the source said.

Yet another source says that the nannies Britney hires are not so much required to be have childcare experience, but rather be ‘young and fun’ who like to ‘drink and party’.

"She just cares about whether they're young and fun and like to drink and party. She hires people to be her friends,” the source told the mag.
