Brooks Nader loses bikini top — again — and gets cozy with model Jack Lumsden on yacht in Positano

When it comes to Brooks Nader, a bikini top is always optional.

The “Baywatch” star, 29, once again ditched her top while on a luxury yacht in Positano, Italy with model Jack Lumsden on Thursday.

In pics obtained by Page Six, Nader hugged a shirtless Lumsden close while wearing a white eyelet bikini top, then later took it off while another male friend hilariously tried it on.

Nader was in danger of a wardrobe malfunction, as her towel hung low around her breasts.

More glam shots of Nader included her smiling big with a drink in hand, and her striking a picture-perfect pose while leaning over the yacht’s railing sporting big black sunglasses.

The “Love Thy Nader” star wore her bleach blonde hair down in the glam snaps.

Nader has been having plenty of fun with Lumsden, though they haven’t confirmed their relationship. They were previously snapped cuddling on their yacht in Capri, Italy. She wore a plunging black swimsuit as the two enjoyed the sunshine with friends.

Last Sunday, she was snapped boldly baring her breasts in front of her family while in Sardinia, Italy in pics obtained by Page Six.

Nader wore nothing but a skimpy crochet bottom as she jumped into the ocean and spent time on a yacht with her mom, Holland, her dad, Breaux, and her 24-year-old sister, Sarah Jane.

Despite Nader ditching her bikini top on multiple occasions during her epic Italian getaway, she shared back in May that she wasn’t even allowed to wear a bikini growing up.

“Well, [my parents are] pumped about ‘Baywatch’ because it’s a one-piece — we weren’t allowed to wear two-piece bikinis growing up,” Nader told Fox News Digital. “So they’re like, ‘You’re following the family rules. You’re wearing a one-piece. So, we’re all good.’”

Nader was last linked to actor Taron Egerton, 36, after they were snapped showing plenty of PDA, though in June she insisted she was single.

“I’m just single, having fun, always,” she told TMZ. “I’m just going on fun dates, but not with anyone right now.”

Nader was previously marred to Bill Haire, but they divorced in 2024 after four years of marriage.

She’s also been linked to NFL star Tom Brady, Oscar winner Kevin Costner and her “Dancing With the Stars” partner Gleb Savchenko.
