Heidi Klum: I Saved My Kids' Hair For Art Projects!

Heidi Klum walks hand in hand with her boyfriend/bodyguard Martin Kirsten while doing some retail therapy on Friday (June 28) in New York City.

The next day, Heidi was spotted spending time with her children and mom Erna at a park in the Big Apple.

Earlier in the week, Heidi donned three different outfits while out and about in the Big Apple.

“So two of my boys, they have big afros, and when I shaved them all down, I kept all the hair and I put it in a Ziploc bag. I keep everything! But then, I waited and I’m like, ‘I don’t know what I’m gonna do with this.’ It was so beautiful, this whole bag of afro: one for Henry, one for Johan. The next time they painted their faces, I glued all their hair around it, so it was like this three-dimensional painting. It’s their face!” Heidi recently shared to Us Weekly.

FYI: Henry is wearing a John Varvatos Boy’s Collection t-shirt.
