Happy Birthday, Cindy Crawford!

The legendary supermodel rang in birthday No. 50 in St. Bart's on Saturday, but judging by her still-flawless figure, you'd never guess it.

In honor of her special day, we've rounded up all the times this past year Crawford has stunned us with her sexy physique and proved that age is nothing but a number.

That time she re-created a commercial she filmed in her 20's.

In 1992, Crawford, who was in her early 20s at the time, starred in a Pepsi Super Bowl commercial. The brunette beauty re-created the iconic ad earlier this month with James Corden for "The Late Late Show." Needless to say, she looked just as beautiful in her tight-fitting top and short denim shorts two decades later.

As Pepsi puts it, "New look, same great taste."

When it comes to red carpets, she's still considered royalty.

The birthday girl turned heads on the red carpet at the Golden Globes in January 2015, donning a gorgeous bright blue gown featuring a thigh-slit. Once again, she proved she's fit and fabulous!

Her photoshoot pics are just as intriguing.

We seriously couldn't take our eyes off Crawford's sultry black-and-white photos from the February issue of United Airlines' Rhapsody magazine.

Ahead of her 50th birthday, she told the glossy that each time she thinks about stepping out of the fashion world for good, a new gig presents itself. "Every year, I tell my kids I'm retiring," she explained. "It's a running joke in our family. And yet every year, opportunities pop up that really excite me."

Well, we'll take all the Crawford we can get!

Her wardrobe is filled with on-trend pieces.

Dressed down, she makes just as powerful of a fashion statement. Just check her out in these flared jeans, which she styled ever so perfectly with a graphic T-shirt, trendy sunglasses and an edgy leather jacket!

Her kids think it's cool to party with her.

Crawford has two beautiful children -- Kaia, 14, and Presley, 16, -- with her husband, Rande Gerber, and clearly they've gotten their good looks from their supermodel mama.

Crawford's lookalike daughter is already following in her footsteps (she recently modeled in Teen Vogue) and the two frequently attend industry parties together.

She's picked up on the selfie phenomenon.

Can we talk about the mother-daughter duo's smooth, soft skin? When it comes to taking selfies, Crawford is clearly a pro (and her skin gives us serious beauty envy).

She's still a bikini-clad goddess.

Two days before her milestone birthday, the model showed off her impeccable abs and toned arms in a sexy string bikini while vacationing with her husband.

The couple has proven they're still head over heels for one another, frequently posting pics of themselves embracing in sweet kisses.

Judging by one of Crawford's latest Instagram posts, she seems to be ecstatic over turning one year older. On Thursday, she posted a throwback photo of herself blowing out the candles on her very chic Vogue magazine birthday cake.

"#TBT My 21st birthday. The cake says "What's Next?"-- now I know!" she captioned it.

We can only hope we'll all age just as gracefully as the stunning star!
