Heidi Klum makes her relationship with Vito Schnabel official on Instagram

Though they were spotted kissing earlier in the year, Heidi Klum has kept mum about her romance with 28-year-old Vito Schnabel until recently.

Heidi, 41, has now gone public, posting an Instagram snap of herself and the curly haired art dealer with a series of gushy emoticons.

Both in hats and sunglasses, the German model and her New York-based love are drenched in sunshine in the shot. The pair are enjoying a yachting adventure to celebrate Vito’s 28th birthday.

The handsome couple first went public in March when Heidi was seen kissing Vito on the dancefloor of LA club 1 Oak at Vanity Fair’s Oscars afterparty.

The German model also added a sea view snap entitled "Beautiful "

Heidi’s new relationship comes months after she split from her bodyguard boyfriend Martin Kristen. Her seven-year marriage to Seal ended in January 2012.

Vito, meanwhile, was previously linked with actress Demi Moore in 2012, as well as with Liv Tyler and Elle Macpherson.
