Heidi Klum received a most unwanted gift from her children earlier this month. She talked about the “gift” on a recent episode of The Ellen DeGeneres Show.

They didn’t give her flowers, or candy, or even a homemade piece of art. No, indeed. Heidi Klum’s children gave her lice–and sometimes it’s the gift that keeps on giving.

“I’m actually lice-free now as of a few days ago,” Heidi Klum told Ellen on Wednesday’s show.

“My daughter was itching and then she had to go to the nurse and then they looked and sure enough they found a little egg, and I mean they’re beyond small, so we had the lice fairies come over to our house,” she shared.

Yes, Heidi Klum even used her imagination when ridding her children–and herself–of the troublesome bugs.

“There are these fairies that come to the house and brush you for hours and get all of these lice out of your hair,” she joked. “They’re fairies. You do get a certificate from the lice fairies when you go to the school because the school wants to know.”

Head lice are actually quite common in school aged children. They aren’t a sign of poor hygiene.

Aside from being a nuisance, lice are harmless, too.

What a nuisance it must have been for Heidi Klum to make sure she and all four of her kids were free from the pesky creatures.

Heidi Klum shares children Leni, 11, Henry, 10, Johan, nine, and Lou, six, with ex-husband Seal, who is likely grateful he has no hair on his head. That no doubt helped prevent him from sharing Heidi’s gift.
