In fact, the redheaded beauty tells Allure's November issue that she's embraced being middle-aged and believes other stars should do so as well.
"I'm always shocked by people who talk about not being middle-aged," says Moore, who poses for the cover in little more than a slash of blue-red lipstick and a hint of a black spaghetti strap gracing her bare, freckled shoulders.
"I'm like, 'How old do you think you're going to live? Let's double your age and see where you get.' People are always like, 'Thirty-five is not middle-aged.' I'm like, 'Double it.'"
The "Kids Are Alright" star -- who owes her youthful glow to staying out of the sun as well as Rodin Olio Lusso, Josie Maran Argan Oil, and using "Oil of Olay with SPF 15 for 25 years" -- is equally blunt when it comes to celebrities who have plastic surgery.
"I hate to condemn people for doing it, but I don't believe it makes people look better. I think it just makes them look like they had something done to their face, and I don't think we instinctively find that appealing," she says.
Moore does admit to touching up her signature red hair with a vegetable-based rinse every four weeks, if only because her gray streak has taken on an unusual hue.
"Redheads don't go gray -- they go sort of peach, unfortunately," she explains. "You don't turn that nice silvery color."
As with her provocative Bulgari ads, Moore -- who recently signed on as the face of Talbots and jokingly refers to herself as "the hundred-year-old-model" -- shows off plenty of perfectly pale skin in the issue's accompanying Tom Munro-shot portfolio.
In one shot, she flashes a bare leg and her toned arms in a slinky Lanvin snakeskin-print silk gown, metal-and-glass necklace, and patent-leather wedges.
In another, she poses dreamily in a cutout Hervé Léger by Max Azria bathing suit paired with a fox-fur Gucci jacket and gold-and-Lucite Alexis Bittar ring.
When not working, the mother of two prefers to keep things casual and conducted her Allure interview in a floppy hat, R by 45rpm plaid shirt, Tom Ford sunglasses, and Birkenstocks -- a look that would make her pal Ellen Barkin shudder.
"She thinks I'm dumpy," admits Moore. "She doesn't like my Birkenstocks. She'd hate this outfit that I have on."
