Britney’s soon-to-be Fed Ex is banking that the former Pop Princess’ recent balding meltdown will leave him smiling on his way out of Family Court.

“He is just waiting for her to get worse,” a pal said. “She is only hurting herself right now.”

Experts warned yesterday that her erratic antics could land her under a psychiatric microscope in the custody fight:

“It’s bizarre behavior,” said L.A. attorney Nathan Goldberg. “It might raise concerns about where the behavior is coming from. … What problems is she having, and how might those problems affect her ability as a parent?”

“The custody evaluator will want to observe each of them interacting with the children to see how they behave with the children and how the children relate to them,” said Goldberg.

“You can’t get any more raw than seeing people battle over their babies.”
