Heidi Klum is all about sun safety.

On Wednesday, May 21, the supermodel shared a video of her husband, Tom Kaulitz, slathering what is presumably sunscreen on her bare butt, which is left exposed by her bikini bottoms.

Klum is seen laying on a pool chair next to a sparkling body of water and giggling as Kaulitz applies the cream. She wears a red thong swimsuit and red baseball cap.

“Lucky me 🥰,” the Project Runway host, 51, wrote in the caption.

Kaulitz, 35, wears leopard-print swim shorts and a dark-colored baseball cap.

It’s not clear where the couple are soaking up the sun, but on May 13, Klum attended the Partir Un Jour (Leave One Day) screening and opening ceremony at the 78th Cannes Film Festival. The model shirked the newly imposed festival dress code and opted for a massive pink floral Elie Saab gown.

The ensemble featured layers of pink organza, cut to mimic delicate floral petals, as well as a strapless neckline and a leg-baring side slit that extended in to a long train.

The Cannes Film Festival official FAQ website reads, “nudity is prohibited on the red carpet, as well as in any other area of the festival,” due to “decency reasons.” The rules further note that “voluminous outfits, in particular those with a large train, that hinder the proper flow of traffic of guests and complicate seating in the theater are not permitted.”

For the Mission Impossible: The Final Reckoning screening on May 14, Klum took the carpet in a cleavage-baring sequin gown alongside Kaulitz, who opted for a classic black suit.

Klum and Kaulitz began dating in 2018 — a few years after she finalized her divorce from Seal, with whom she shares her four kids: Leni, 20, Henry, 19, Johan, 18, and Lou, 15. The pair secretly tied the knot in February 2019.

On Monday, May 5, Klum made her return to the Met Gala after a 12-year hiatus. She told InStyle that she didn’t see her custom Vetements gown until three days before the big event. The simple black gown featured a strapless neckline and flowing train.

“I saw my look for the first time just three days ago,” she told the publication before the special occasion.

“I never got the sketch, photo, or video of my look in the process of it being created,” the former Victoria’s Secret Angel said. “But, since I was working with Guram Gvasalia of Vetements — a designer I fully believe in and trust his vision — I was sure he would create the best look possible.”

When explaining how her dress fit the theme of “Superfine: Tailoring Black Style,” the model said, “The look is all about luxurious fabric, tailoring, and a unique silhouette.”
