Heidi Klum Squeezes into a Latex Skirt That Shows Off Her Thong in BTS Video of Photo Shoot

Heidi Klum is not afraid of a fashion challenge.

The supermodel, 52, took to Instagram to share the behind-the-scenes of a recent photo shoot, which included squeezing herself into a muted pink sheer latex skirt. In a video included in the Tuesday, Nov. 25, carousel, Klum is facing away from the camera and being zipped into the skin-tight garment, which she's wearing over a matching thong bodysuit.

"Is it gonna close?" the model asks as two people work to zip up the skirt. When they're successful, someone off camera exclaims, "It's closed!"

Klum is then seen wiggling her hips in celebration.

In the first video in the carousel, the Project Runway host shows off a room full of clothes, shoes and jewelry for the shoot. "Are we gonna find something in here?" she jokes.

It's not totally clear what project Klum has cooking up, but at the beginning of the clip, she hints that "more music" is coming (in 2024, the model released a cover of the 1980s classic "Sunglasses at Night," originally by Corey Hart). Another post in the carousel shows Klum cheekily revealing that Diplo is with her on set, hinting at a collaboration between the two.

In another clip, Klum tries on a black-and-tan bodysuit and black leather jacket.

"Do you like it?" she asks, before adding, "My ass is out a little bit."

The queen of Halloween recently celebrated her favorite holiday by dressing up as the mythological Medusa, debuting her transformative look at her annual Halloween party in New York City on Friday, Oct. 31.

Her husband, Tom Kaulitz, was dressed as a Greek soldier turned to stone. According to Greek mythology, anyone who looks upon the hideous Medusa turns to stone.

On the red carpet, Kaulitz told PEOPLE that he found Klum's costume to be "sexy."

"I think he looks super hot," Klum adds of her husband's costume.

"HAPPY HEIDIWEEN 🐍Don’t stare too long or you’ll turn to stone," the former Victoria's Secret Angel captioned an Instagram Reel showing off the costume.

The intricate Medusa costume was complete with a long tail and moving snakes that replaced her hair. She hissed at the gathered red carpet photographers and pointed a bow and arrow as she posed for pictures.

Klum started sharing photos and videos of the makeup process early in the day on Halloween, even tagging the makeup designer Mike Marino to give him credit for his work. Marino is a three-time Oscar nominee thanks to his work on The Batman, Coming 2 America and A Different Man. He also won an Emmy for his work in transforming Colin Farrell into The Penguin.
