Heidi Klum's 'rug burn'

Heidi Klum's 'rug burn'

Heidi Klum says the unsightly grazes on her knees are down to "rug burn".

The Victoria's Secret model - who raises three children with her husband, British singer Seal - admits she incurred the marks on her legs, which she has insured for a staggering $2 million, while shooting a commercial.

She said: "My legs are not looking good right now. I wish my pants weren't so tight, I could show you. I have the worst rug burn, but not from the kind of rug burn you're thinking! I just did a commercial and was jumping off tables onto a rug."

Heidi also said the "other kind" of rug burn, which can occur during certain sexual acts, is not uncommon in her household.

She added to US TV show 'Extra': "I think Seal's hot and that's all there is to it. We have fun together!"

Heidi - who has previously dressed up as a cat and a snake for Halloween - recently revealed she is planning another unique creation to celebrate the spooky holiday (31.10.08).

She said: "I try to top myself every year with an outrageous outfit!"

The 35-year-old beauty said her children, Leni, Henry and Johan, have been busy creating their own costumes.

She added: "Leni will be a bumblebee and the boys are both going to be Superman. Johan is completely easy and he'll be anything. He doesn't care!"
