The UK's Daily Mail reports that Demi Moore has spent almost a half million dollars on plastic surgery, injections, lipo, and more in order to get and keep her bangin' bod in shape for movie roles. The roles, unfortunately for Demi's wallet, just haven't materialized, and now she's speaking out against Hollywood's obsession with youth.

The 44-year-old told a magazine: "It's been a challenging few years, being the age I am. Almost to the point where I felt like, well, they don't know what to do with me. I am not 20. Not 30.

"There aren't that many good roles for women over 40. A lot of them don't have much substance, other than being someone's mother or wife."

After a string of flops in the 1990s, she took a career break, during which time she met her current husband, 29-year-old Ashton Kutcher.

Miss Moore then returned to the screen in 2003's Charlie's Angels: Full Throttle, emerging from the sea in a skimpy bikini which showed off the results of a cosmetic surgery spending spree.

As well as breast implants, collagen injections and liposuction on her hips, thighs and stomach, she had a £5,000 ($10,130.00) procedure to lift the sagging skin on her knees.

She also employed an army of advisers - including a nutritionist, personal trainer, yoga teacher and kick-boxing coach.

"If we are told we are not valuable once we hit 30, it is a problem," she said. "We all have more to give.

"We can't just wait for something to happen. We have to say, 'I'm mad as hell and I'm not going to take it any more'."

I'm sure she must also feel a bit of pressure to stay hot for her much younger hubby, Ashton Kutcher, who is also much in demand in the Hollywood machine.
