Anna Nicole reveals all about TrimSpa diet

Anna Nicole Smith has exploded the myth about her famous diet plan. It's all down to pills, colonics and hours on the toilet.

The busty model, who slurred and stumbled her way through a speech at the American music awards on Sunday, reportedly lost 69lbs on the TrimSpa diet, and has always insisted the plan is in no way harmful.

But, in a new interview which will air tonight on news show Entertainment Tonight, Smith admits the diet has taken its toll on her.

She says: "You eat, like, small portions and you do it for, like, two weeks, and also they have a colon cleanser and you're just, like, on the pot all the time… You lose that weight quickly.

"I do take two pills a day to maintain (the diet), you know."

Also in the candid interview, Anna Nicole admits she took painkillers after the death of her oil tycoon husband, J Howard Marshall, and went into a coma.

She adds: "I almost died. I had to learn how to walk again and all this and that. It was hard and if you have to go into rehab, it is not fun.

"They tear you down. They tell you you're nothing. They say you're crap. They say stuff like: 'You're no better than anybody else.' It's just horrible."
