Wearing her blonde tresses down, the TV star, who is currently taking a break from Germany’s Next Top Model, sported a wet T-shirt complete with a heart and ‘Chill Out’ motif.
Despite her top half remaining covered, Heidi’s trim stomach could still be seen after she took a dip in the sea with her hunky man.
Heidi chose a simple pair of black bikini bottoms and a two-tone halterneck for her relaxing day, before later adding a sheer sarong to her attire.

The mother-of-four did however make sure to remind fans to watch America’s Got Talent, in which she appears alongside fellow judges Mel B, Howard Stern and Howie Mandel.
She tweeted: “What a way to end @nbcagt! @Freckled_Sky_ were stellar! #innovative#goldenbuzzer #straighttoradiocitymusichall #howardbeatmetoit #AGT.”

Vito has previously been linked to a few other famous faces, including Demi Moore, Liv Tyler and Elle McPherson.
Heidi first became involved with the curator following her split from bodyguard boyfriend Martin Kristen, which came after her divorce from singer Seal.
