Demi Moore is giving a candid interview to U.K.’s Red Magazine, saying that Hollywood “doesn’t know what to do with her” now that she’s past age 40.

“It's been a challenging few years, being the age I am, with so much focus now on how I look. Almost to the point where I felt like, well, they don't know what to do with me. I'm not 20. Not 30,” she says.

She adds, “For many female actors, who turn 40, it means the end of their career, it's time to retire. 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. If we are told we are not valuable once we hit 30, it is a problem. We all have more to give. We can't just bend over and wait for something to happen. We have to say, 'I'm mad as hell and I'm not going to take it any more.'"

Demi, 45, has been married to Ashton Kutcher, 29, since 2005. Ashton has often been called “M.O.D.” (My Other Dad) by Demi’s three children with Bruce Willis.

"Bruce is a wonderful father,” says Demi. “He's present and he's involved. It is in a very different form than the traditional, but I feel that my children have a father who is present, so they don't need someone to replace him.”

So does that mean there are more kids in the future for Demi and Ashton?

"Once you hit three [children] and you're outnumbered, it's really like, 'What's the difference between three or four or five?'" she says.

“Ugly Betty’s” Vanessa Williams has it all!

Besides being a gorgeous actress and singer, the mother of four has been nominated for her first Emmy Award for her role on “Ugly Betty.”

So does Vanessa have a special man in her life to share it with?

“Between four kids and these hours, squeezing a man in right now is impossible,” she reveals. “I'm open for opportunities. Bring it on in!”

She is a stunning actress with youthful beauty, and 49-year-old Michelle Pfeiffer is sitting down with “Extra” to get surprisingly candid about age in Hollywood.

Michelle plays an aging witch searching for eternal youth in the new movie “Stardust,” which she claimed is a quest she can relate to.

“You know, I think as you get older, the more obsessed you become,” the graceful beauty admitted.

Gorgeous Michelle Pfeiffer is finally making her return to the big screen, starring in this summer’s musical comedy “Hairspray” with John Travolta.

She hasn’t made a major film since 2002’s “White Oleander,” but now Michelle is back – with a vengeance! She’s playing a former beauty queen turned stage mom from Hell in the musical.

“In the beginning it didn't feel like fun,” Pfeiffer admitted. “After I had signed on to do it, it suddenly occurred to me that I was playing a racist.”

Twenty-four years after they made rock-and-roll history together appearing as husband and wife in his “Uptown Girl” music video, Billy Joel and his ex, supermodel Christie Brinkley, came face-to-face last night at their daughter’s concert – and it was all family harmony!

“We’re friends,” Christie told us. “Billy and I are friends.”

Christie, 53, and Billy, 58, were married for 10 years before divorcing in 1994, and Christie insists there is still no bad blood between them.

Christie Brinkley is sitting down with “Extra” to talk for the first time about the accident that nearly crippled her.

In an exclusive one-on-one, she revealed details about the Aspen ski trip that went terribly wrong.

“I was really lucky,” Christie explained.

After she fell while skiing in Aspen, Brinkley noticed something was wrong.
