Heidi Heidi Klum Poses Nude

She’s pushing 40 and is a mother of four – but Heidi Klum isn’t afraid to bare it all.

The supermodel, 38, poses nude in Allure’s May issue, showing off her toned physique and discussing why she’s never gone under the knife.

I’m proud to be able to say, in this day and age, I haven’t done anything,” Klum tells the magazine.
