Watch out ladies!

Former model Paulina Porizkova is putting most twentysomethings to shame!

The 50-year-old supermodel took to Twitter earlier today to share a sexy bikini pic of herself on vacation. “Florida, time off. #brian Magallones #fiftynomakeup,” the beauty captioned the hot shot.

Stunning in a chic black-and-blue bikini, Paulina looks half her age as she relaxes in the pool while on vacation in Florida. Is Paulina out to prove that SI Swimsuit models seemingly never age?

According to SI, Paulina is arguably best known for her back-to-back Swimsuit covers in 1984 and 1985. But at this rate, she may be well on her way to being best remembered for making 50 the new 25. If anyone was looking for a sign that age really is just a number, Paulina’s Twitpics are all the proof you should need.

Porizkova told PEOPLE that when she was rising to fame in her 20s, she didn’t take good care of her skin.

“I was a nightmare,” she said. “I’m a product *****, so anything you gave me, I experimented with. I drank, I smoked, I’d tumble into bed with a full face of makeup on and go to work and say, ‘Look, I’m already done up.’ Sometimes it worked, sometimes it didn’t.”

Now, the star pays more attention to her routine, and never leaves the house without SPF.

“I went to a party for Estée Lauder … they had some scientists there, and I said, ‘What’s the good stuff? What’s the stuff I really need to use?’ Both of them looked at me and said, ‘Use SPF,” she said. “And I’ve used it every day since. I feel like a vampire if I go out without it.”

Porizkova turned 50 just last month and it’s safe to say she’s held on to every ounce of her signature good looks and beauty.
