Heidi Klum has let loose and bared it all — once again — on her St. Barts vacation with husband Tom Kaulitz.

The supermodel, 52, was photographed going topless during her beach outing with the Tokio Hotel rocker, 36, on Sunday.

Though her top half was completely bared to the sun, she covered her lower half in a pair of tiny white and red cherry-printed bikini bottoms.

She wore a pair of white shades as she stepped out in the sun, letting her long wet hair hang loose down her back. She also rocked a dainty silver necklace for the outing.

Kaulitz walked by his wife’s side through the clear waters in a pair of cheetah-print swim trunks.

The “America’s Got Talent” judge is clearly letting it all hang out as she blows off steam on her holiday vacation.

She was also spotted ditching her bikini top at the beach last Friday. For that excursion, she chose a pair of brown thong bikini bottoms.

Several snapshots showed her sipping on a beer as she joined her husband in the water. At one point, the lovebirds even shared some PDA and locked lips as they swam.

On Sunday, Klum put her love for her beau on display by sporting a towel decorated with a huge rendering of her husband’s face.

The couple jetted off to St. Barts last week after enjoying Christmas in New York City. Klum previously gave her followers a glimpse at her holiday plans when she shared a picture of them hugging in front of the Rockefeller Center Christmas tree last Thursday.

She also posted a video of them holding hands while ice skating, wearing festive red and white plaid pajamas, winter coats and Santa hats.

The couple has been married since February 2019.
