Britney Spears has been having panic attacks about her upcoming tour. Britney apparently feels so out of shape and out of practice that she’s been “throwing tantrums” and “locking herself in the bathroom.” A lot of this stress comes from the paralyzing fear she won’t be able to travel with her children. Kevin Federline’s lawyers are trying to milk the pop star for even more money before they allow her to uproot Sean Preston and Jayden James. Right now she’s slated to give him $4,000 a week for the 10 weeks she’s on tour!

The Sun is reporting:

Britney is in danger of not going on tour as she has been having paralysing panic attacks. Every time there is a crisis, Britney screams and cries and locks herself in her room. She has been telling her doctor she feels under pressure and ill when she thinks about touring. She is worried about being on the road without her kids, and fears that her performance will be branded a flop.”

Aw. Poor Brit Brit, but her craziness is the gift that keeps on giving.
