Eternally Ripped

We're loyal to our favorite stars through thick and thin, but a select few never go through the thick period. See the stars with hard bodies that just don't quit.

The fountain of celebrity youth takes many different forms. It can be as unprepossessing as a Beverly Hills medical office and as in-your-face as a Ricky Martin Miami Beach workout. Then there are those celebrities who have figured out how to continue living la vida loca well into their 40's, 50's and 60's, but still look like a million bucks. In finding a way to be eternally coddled, eternally exfoliated and eternally exercised, these lucky limelighters also manage to be eternally irritating.

Who's working out and who's being worked on?

Madonna

Madonna will be eternally ripped for 'Shanghai Surprise' and 'Swept Away.' But as per her saucy recent shtick on 'Late Nite with David Letterman,' she still has a body Sandra Bernhard would kill for.

Demi Moore

Regardless of what you think about Ashton Kutcher's acting abilities, most women label him a hottie. Which means Demi Moore had to trample over a lot of young groupies to get to the front of the line.

Bruce Willis

Demi's ex, Bruce Willis, isn't ageing too badly either. Although he might want to wait and see how "Indiana Jones 4" and "Rocky VI" do before he tackles that long-rumored sequel "Die Hard 4.0."

Halle Berry

Although her taste in men and driving abilities may be the subject of ongoing debate, there's no doubt Halle Berry is right up there with Ursula Andress in the bikini-clad Bond girl Hall of Fame.

Kate Moss

There's an obvious 'Eternally Ripped' double entendre here. But seriously, was there a bigger establishment hypocrisy than the fashion industry consternation over Kate Moss getting caught doing drugs?

Sylvester Stallone
