Over the hill? We don’t think so. These 40-something starlets have made looking young look easy. Check out our list of Top 10 Hottest Female Celebrities Over 40 who put babes half their age to shame, and get the dirt on whether their youthful good looks are natural or plastic-surgeon-provided.

They don’t call Elle MacPherson “The Body” for nothing. Still, this down unda beauty claims to be all natural (don’t you just hate her?). According to Celebrity Cosmetic Surgery, Elle stated, “It hasn't occurred to me to intervene with the course of nature to date. I have a strong aversion to putting anything artificial inside my body. I don't even take aspirin."

Hey, whatever works!

Perhaps being married to someone almost half her age keeps Demi Moore young…yeah, right. We all know this actress’s secret to eternal youth: Demi is rumored to have spent almost half a million dollars on plastic surgery. Feeling the pressure of Hollywood, Demi reportedly underwent a head to toe (or knee) makeover for her role in Charlie’s Angels. The Daily Mail reports that Demi had breast implants, collagen injections and liposuction on her hips, thighs and stomach, and she had a procedure to lift the sagging skin on her knees.

Unfortunately, except for keeping her cutie hubby Ashton Kutcher interested, it hasn’t done her much good. Says Demi, "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."

A natural glowing beauty from the inside out, will this mom-to-be get some work done after she pops her baby out? Not likely. According to Female First, Halle Berry called anyone who opts for a little retouching “insane.” She added that “It's like a slippery slope - once you start you pull one thing one way and think ‘God, I've got to do the other side.’ There is this plastic, copycat look evolving and that's frightening me."

Guess Halle’s choosing to forget those rumors that she herself has had a nose job. Really, though, what’s frightening us lately is that Shirley Temple hairstyle she’s been sporting – though that’s pretty much the only thing we can find fault with on this gorgeous gal.

What lies beneath? We bet it’s a little Botox…shhh! Although not opposed to plastic surgery, Michelle Pfeiffer claims she isn’t ready just yet. Celebrity Cosmetic Surgery reported that the pushing-50 actress has said, “When I’m rested, I look pretty darn OK. I can hold off on that facelift for another few years. [But] when I’m feeling weary, then I think, maybe I better make that appointment.”

In the meantime, we think she looks pretty darn fantastic, surgery or not.

Apparently not even the stress of your best friend stealing your husband can age this “Melrose Place” hottie. Looking good is the best revenge, after all. Although we suspect Heather Locklear’s had some work done, she’s keeping her lips tight…and plump.

She told Allure, "I think [plastic surgery] is great! Especially since I'm at an age now where all my friends talk about it. No one's done it yet, but it's all they talk about: 'What do you think? Should I do it?' I go, 'You're not going to get a face-lift, not yet.' It's a little scary, too, because I think the big-boobs-and-big-lips look is kind of dated now—a little '80s, not too sophisticated.”

But Locklear admits that she sometimes she toys with the thought of getting rid of her slight turkey gobble. Don’t bother, Heather, you’ve already dropped the turkey—ahem, Richie.

Dating a cancer survivor, getting dumped, and then getting cancer herself can’t bring this songstress down. And don’t expect plastic surgery to be Sheryl Crow’s “greatest mistake” anytime soon either…especially on her small bits. She told Star Pulse, "What's wrong with being a flat-chested girl? I think boys should feel good about the option of dating a girl who doesn't have big boobs! The plastic surgery thing is probably not my bag, ever."

We can tell all this gal wants to do is have some fun and soak up the sun…sans any nips and tucks. Thankfully, she doesn’t need any!

This cougar’s younger hubby is keeping this actress youthful the natural way…literally! According to Celebrity Cosmetic Surgery, David Arquette has banned his wife from having plastic surgery. Although Court is ready for a few tucks, David isn’t having it. But there is one thing she can’t stand about her body: "I have a permanent baby belly after having Coco and I have issues with getting older. I obsess over the changes. David has a huge problem with surgery, but I don't."

We say ditch the husband and get the surgery if you really want it (not that you need it, girl). Although we’re sure chasing after two kids (cough, David, cough) keeps Courteney Cox looking young, too!

She may be Miss Congeniality, but this beauty queen insists on aging naturally. Glamour asked Sandra Bullock if she’d even consider plastic surgery, to which she adamantly responded, “I wouldn’t do it. Period. You won’t find one woman in our family, not a one, who would consider plastic surgery, and I’m telling you, I have a family of the sexiest, smartest, funniest, most beautiful set of women. As my 80-year-old Aunt Luddy says, ‘If you’re 80, and you live your life like you’re 80, then you’ll look 80. If you’re 80, and you live your life like you’re 50, then you’ll look 50.’ Aunt Luddy looks 45. I’m not saying, I don’t condone plastic surgery. But if you do it, then do it well, make sure you come out looking like yourself. You’re comfortable being put under a knife and being disemboweled? Great!”

She may have been Unfaithful, but this beautiful actress doesn’t have anything to apologize for. Of plastic surgery, she tells More, "I don't feel that apologetic yet. I feel like you're apologizing if you have plastic surgery, apologizing for nature and history and experience. I take comfort that aging happens to everybody. It's part of life. Aging offers great lessons in dignity, since the indignity wins in the end. Yes, it bothers me when I have lines or puffiness or droops. But it connects me with the human race. Like weather bringing people together, aging brings people together."

With a body like that (not to mention a hottie husband like Josh Brolin), who cares?

No, Elizabeth Hurley hasn’t made a pact with the devil, but we suspect she’s made one with her plastic surgeon. Hurley says that she hasn’t had any Botox yet, but thinks it may be time. “I haven’t had anything done yet,” she claims. “Look I’m frowning. I don’t have anything in my face. But I would never rule it out.”

Despite being “natural” in her face, Make Me Heal speculates that she’s had lipo and a breast augmentation. And it definitely looks like she had Botox and perhaps some lip collagen done, whether she wants to admit it or not. Forget diamonds—denial is a girl’s best friend!
