The 43-year-old actress is shown in her latest magazine photo-shoot without cosmetics, the aid of a hairdresser or a fashionable outfit - and has said she is on a mission to shatter beauty myths.

I don't have great thighs, I have very big breasts and a soft, fatty little tummy

Jamie Lee Curtis

Appearing in the new edition of More magazine in the US, Curtis said that treatments like liposuction and Botox injections did not produce the results often claimed.

"I've had a little lipo. I've had a little Botox. And you know what? None of it works. None of it," she said.

The actress, who once played a shapely aerobics instructor in the film Perfect and showed her breasts in Trading Places, called her personal beauty "a fraud".

"People assume I'm walking around in little spaghetti-strap dresses.

"It's the insidious Glam Jamie Jamie, the Perfect Jamie, the great figure, blah, blah, blah - it's such a fraud," she told the magazine.

She asked for a more honest photo-shoot to balance her public image.

She also starred in Fierce Creatures with John Cleese

She also said showing her real body was part of her recovery plan for addiction problems.

"In the recovery program I'm in for addiction problems, they talk about peeling an onion, exposing more layers."

Curtis is promoting her fifth children's book, I'm Gonna Like Me: Letting Off a Little Self-Esteem, which will be in US bookshops later in August.

The actress, best-known to filmgoers for starring in Halloween and A Fish Called Wanda, has just completed a new film, Daddy And Them, with Billy Bob Thornton.
