Britney Spears BritneyPanic.jpgBritney Spears has reportedly been suffering from panic attacks that have led to "tantrums and locking herself in the bathroom," according to The Sun newspaper.

The paper quotes an unnamed source as saying: "She has been telling her doctor she feels under pressure and ill when she thinks about touring."

Brit's dad Jamie has reportedly consulted doctors about her condition.

“Every time there is a crisis, Britney screams and cries and locks herself in her room," another source told the newspaper.

Certainly there is a TON of pressure on Britney, and all of the legal drama with former manager Sam Lutfi really can't be helping.
