THE Swimsuit illustrated by Sports The star has previously opened up about how much she loves being naked at home, so much so that her kids have to remind her when they have friends over.

In an interview on Call her daddy with Alex Cooper, Klum said, “I mean, I try to be like that with my kids. Obviously, when you know, there’s no one there. I’m in my backyard too, you know, I’m topless. And they’ll come, like, ‘You know, my friend’s coming, mom, put on your top.’ And I’m like, “When have I never worn a top when your friend came over? Of course I will.”

She added: “But they always make sure. ‘Mom, just a little warning about what’s going to happen here.’ And I say, ‘Don’t worry.’ I don’t want to show someone just for the sake of showing someone, I just don’t like tan lines.”
