10 Gorgeous 40-Year-Old Stars Who Defy Their Age (PHOTOS)

Forty is a weird age for women. It's society's fault. We think we have it so much better when we're young. Youth is good times without the need for a really good moisturizer, that's certain, but 40 is fabulous. Sexual peak comes at 30; at 40, we have the sex, the looks, the brains, and the knowledge of the years we've lived. Provided we've taken care of ourselves. 

Having dreaded turning 40 myself, I hit it and then saw the previews for This Is 40. Perfect, I thought! Laughing is better than frowning when it comes to keeping wrinkles away.

I turned 40 in really good-looking company, with women who defy their age. Look at Cameron Diaz — 40 and stunning. Her hands, her clavicle, her decolletage! You can tell she moisturizes. Let's take a look at the other gorgeous, confident, put together, smart, and beautifully seasoned ladies who hit the big 4-0 this year. They'll make anyone younger no longer afraid to age.

I have a major girl crush on This Is 40 star Leslie Mann. She's like the Tina Fey of movies, where Tina Fey is the Tina Fey of TV. Tina's got two years on 40-year-old Leslie, but both women are not only beautiful and hilarious, they both got to kiss Paul Rudd on-screen. Lucky!

Alyssa Milano

How did this happen? Wasn't Alyssa Milano a kid on Who's the Boss? about three years ago? It's been a while since those days, but look at this glowing beauty. Forty is charmed.

Thandie Newton

Look at Thandie Newton wearing faux leather leggings (or maybe they are real?). Beautiful woman. Never would have guessed she's 40. But she is. Doing the age proud.

Gabrielle Union

As you can see, Gabrielle Union is in incredible shape. Those arms! Those legs! That form-fitting dress! Can we just all agree she looks younger than some of those chicks on Teen Mom?

Carmen Electra

Maybe Camen Electra's secret to feeling young is dating older men — she's currently linked with 53-year-old Simon Cowell. Whatever she's doing is clearly working.

Gwyneth Paltrow

We like to pick on Gwyneth Paltrow sometimes, but the fact remains that whatever she's doing is working when it comes to getting up there in age. Perhaps it has something to do with all the hot guys she's been with — Brad Pitt, Ben Affleck, and her husband Chris Martin.

Jennifer Garner

I chose this photo of the youthful Jennifer Garner because it so beautifully captures the pure love she has for her daughter. She's a 40-year-old mom of three and gets more gorgeous every year. So does her hubby, the sometimes silver-haired fox Ben Affleck.

Rebecca Romijn

Rebecca Romijn is a 40-year-old mom of twins. Let's fix that sentence up. The sexy Rebecca Romijn is a smoking hot 40-year-old mom of twins. As a twin mom of the same age, this pleases me greatly.

Sofia Vergara

Bubbly, funny, curvy, and seemingly sweet as can be, Sofia Vergara is fabulously fit at 40.
