Heidi Klum ditches bikini top as she sunbathes on holiday vacation in St. Barts

Heidi Klum turned up the heat as she ditched her bikini top while sunbathing in St. Barts.

The supermodel took to Instagram Tuesday to show off her physique while lounging on the beach in nothing but black bikini bottoms and sunglasses.

In the clip, she strategically covers her chest with her hand as she moves the camera to show off her glowing, makeup-free skin and beachy waves.

Klum, who turned the comments off, simply captioned the video with an emoji: “😎.”

The “America’s Got Talent” judge has been showing off her Caribbean holiday vacation with husband Tom Kaulitz.

The duo, who wed in 2019, were seen in a video posted to social media on Christmas Day standing on a wooden swing at the beach as Klum, 50, wore a semi-sheer leopard coverup and a Santa hat.

She also flaunted her Santa hat around the island while driving in a convertible with Kaulitz and an inflatable penguin a day before.

Klum has stayed in the holiday spirit throughout her vacation as she was photographed last week frolicking in the ocean with her husband on an inflatable reindeer floatie while sporting a black thong bikini.

The former Victoria’s Secret model and the musician were first romantically linked in April 2018.

At the time, the couple was seen getting hot and heavy in Cabo San Lucas, Mexico, where Klum also ditched her bikini top.

The blond bombshell and the rocker have garnered attention due to their 16-year age gap, which she claimed she doesn’t “really think about.”

“Lately, I’m being reminded more about my age by people other than myself,” she said in a 2018 interview with InStyle. “My boyfriend is many years younger than me, and lots of people are questioning that and asking about it.”

“That’s really the only time when age seems to be shoved in my face and I have to give an answer for it,” she added.

Klum was previously married to Ric Pipino from 1997 to 2002 and Seal from 2005 to 2014.

She has four kids — Leni, 19, Henry, 18, Johan, 17, and Lou, 14 — from past relationships.
