Gisele Bündchen certainly wasn’t moving at a glacial pace when she was doing a photo shoot in Iceland.

The supermodel, 43, took the icy plunge and revealed a scary ordeal she experienced in 2000 during “The Tonight Show Starring Jimmy Fallon” on Thursday.

“I did a photo shoot on a fake iceberg in Iceland, and I almost fell off into the ocean,” she said during the “True Confessions” segment on the NBC talk show.

The supermodel nearly fell into the freezing cold water and “would have been dead in seconds.”

“So the whole thing I was supposed to be in this slip dress while everyone was like in a boat — like, all the crew was in a boat with like huge puffer jackets and life vests,” Bündchen recalled.

Bündchen was participating in a campaign for the fragrance Oxygene at the time.

Bündchen walked her last runway show after 20 years in 2015. As the face of brands like Chanel, Carolina Herrera and Louis Vuitton, she earned an estimated $386 million throughout her career, and continues to be featured on magazine covers.

“I think I am the farthest I have ever been from retiring. I’ve never worked so hard in my life, actually,” she said during an appearance on “The Ellen DeGeneres Show” in 2018. “I think I’ll retire only the day I die. Because I love working, I love creating, I think that’s why we’re here to keep creating and expanding and learning.”

Elsewhere in the interview Thursday, the Brazilian native opened about her new cookbook, Nourish: Simple Recipes to Empower Your Body and Feed Your Soul.

The book is set to be published on March 26 and is chock-full of healthy recipes.

“You know, I love food. Yes, I really enjoy food. And I had all the playdates were always at my house,” she explained to host Jimmy Fallon, 49.

Bündchen shares kids Ben, 14, and Vivian, 11, with ex-husband Tom Brady, whom she divorced in 2022.

“So, all the kids, you know, the moms would come back and be like, ‘How did you get my kid to eat vegetable?’” she went on.

“I’m like ‘It’s so easy, just, like, roast them.’ She’s like, ‘How do you do that?’ I start sharing recipes with moms and, you know, I have five sisters, so we always share recipes as well.”

It was then that one of her sisters suggested that she compile a cookbook of all of her favorite recipes to share with others.

Bündchen loved the idea and continued to pursue the project.

“Anything that’s good for me, that feels good, I want everyone to know and everyone to have it,” she said.

“So that’s kind of like my way of sharing nutritious, delicious, simple stuff, because I’m not a chef,” she added. “I just want to eat good stuff.”

“Nourish” includes dishes for recipes such as papaya-almond smoothies, Brazilian cheese bread, carrot muffins and steak salad.
