The Britster's former bodyguard, Tony Baretto, is the no-longer-secret witness in her custody battle. The People website says he was ready to testify about the Mother of the Year's penchant for nudity and drug use, and safety issues concerning the kids, but submitted his allegations in written form instead.

In other Britnews, Monday's closed-door hearing was the last for her lawyer, Laura Wasser, who insisted that she wasn't bailing on her client and that her replacement Marci Levine would do a bang-up job as her new attorney. (For the moment, though Kevin Federline is seeking primary physical custody of the kids, he and the lip-syncher are still sharing them 50/50.) Likewise, the management company she hired a month ago to help launch her new album has dropped her, explaining, "Current circumstances have prevented us from properly doing our job."
