Britney Spears' parent coach thinks she's crazy

Troubled Britney Spears' court-appointed parent coach is begging to be taken off the case - because she thinks the star is crazy, according to U.S. reports.

Insiders insist Lisa Hacker, who was assigned to monitor how Britney is with her two sons, is trying to get off the case.

"Ms Hacker wants desperately to be reassigned," a source told Star magazine.

"She stressed that it's not worth endangering her own life for someone who doesn't seem to care what happens to herself.

"She says Britney is crazy and that she can't take it anymore. "This isn't good for her health. "She's a nervous wreck."

Hacker's biggest fears, according to Star, is when Britney drives. Recent pictures have seen her texting while she drives, wearing dark sunglasses at night - and even running red lights.

"The monitor is afraid every time she has to get in the car with Britney," the source old Star.

"It's terrifying because she doesn't pay attention to the road and is either talking or texting on her cell phone."

The source added: "Ms Hacker says her job is to watch Britney while she's with her kids. But Britney's life is just too chaotic."
