Heidi Klum turns 44 next week but she still has the body of a supermodel. She shows it off in a new book, Heidi Klum by Rankin. Photographer Ian Rankin has been taking “intimate naked shots” of Klum for the past ten years, according to the Daily Mail.

“I have posed naked before but I’ve just never showed it to everyone,“ Klum told the Mail. "I feel more confident now than when I was in my twenties.“

Klum and Rankin are old friends and this is their second book together. In 2009, Rankin released a book of non-nude photos of Klum, Heidilicious. Last year, he shot Klum taking a bubble bath for Love magazine’s video advent calendar, and he regularly takes photos of her in lingerie for her company, Heidi Klum Intimates.

The model and photographer were both in London for a book signing today, and Klum still looks “Heidilicious” in the promotional photo:
