Heidi Klum and her husband, Tom Kaulitz, are continuing their ongoing PDA tour of Italy as they made out in the ocean during vacation in Sardinia Tuesday.

Photographers snapped the couple embracing and passionately kissing while they took a dip in the ocean.

They were also seen holding hands while frolicking on the beach.

The 50-year-old showed off her figure in a black bikini with diamond body jewelry that is a custom version of a $15,500 Jacquie Aiche design.

The pair seem to be displaying public affection all over Italy as 33-year-old Kaulitz was caught cradling Klum’s stomach in Venice last month.

Klum’s 13-year-old daughter, Lou, joined the pair in Venice as well.

The model shares Lou, as well as sons Henry, 17, and Johan, 16, with ex-husband, Seal, whom she was married to from May 2005 to October 2014.

The former “Project Runway” host and German musician are not shy when it comes to showing their love for each other. They were also photographed locking lips on a yacht in France in May.

Klum and Kaulitz secretly tied the knot in 2019. The Tokio Hotel rocker popped the question after a little over a year of dating. This is Klum’s third marriage and Kaulitz’s second.

Klum’s eldest child, 19-year-old daughter Leni, not only bears a striking resemblance to her mother but has also followed in her modeling footsteps.

Leni’s biological father is Italian businessman Flavio Briatore, whose relationship with Klum ended while she was still pregnant.

Seal legally adopted Leni in 2009 when she was 5 years old.
