Heidi Klum has stripped down for the cover of a new book.

The supermodel-turned-serial mom recently posed for a series of nude pictures for a soon-to-be-released coffee table book called Heidilicious, which she describes as “very naughty.”

Heidi teamed up with renowned photographer Rankin for the book, which is due to hit stores in October.

“It’s very naughty,” Heidi — who donned just a pair of socks for the cover — told LA Confidential Magazine this year.

The catwalk maven felt comfortable enough to disrobe during several shoots due to her long relationship with the photog.

“I’ve been shooting with this photographer, Rankin, for seven years, and working with him is fun because he always makes me look different. And he always gets me to take my clothes off for some reason,” she added. “We’ll do some job, and then he’ll say, ‘Why don’t we shoot some more things,’ and I’ll wind up without anything on.”
