50 and fabulous!

Supermodel Paulina Porizkova was spotted looking tanned and toned in a blue triangle bikini in St. Barts on Saturday.

The Czech beauty, who turned the big 5-0 on April 9, was joined by her 17-year-old son, Oliver, with husband Ric Ocasek, as they chatted ankle-deep in the Caribbean and splashed in the waves.

Last month, the Sports Illustrated swimsuit veteran shared a makeup-free photo on Twitter of herself sporting the same blue two-piece while relaxing in Florida.

When a commenter joked that she hasn’t aged, Porizkova quipped back, “only not aged when lying down.”

Though the former America’s Next Top Model judge makes aging look effortless, she admits that growing up in the fashion industry led to a bit of a reckless beauty regimen.

“I was a nightmare, she told PEOPLE back in 2012. “I’m a product whore, 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.”

“When I saw the first signs of aging I was like, ‘Ahh,’ ” the mom of two said. “I pulled out every bottle there was. Two hundred bucks? Sure! Three hundred bucks? Sure. Disappointingly, none of them did much.”

The one miracle cream Porizkova can swear by? Sunscreen!

“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?’ ” she recalled. “Both of them looked at me and said, ‘Use SPF.’ And I’ve used it every day since.”
