New Delhi, Mar 6 : Supermodel Heidi Klum has no intentions of leaving the catwalk.

"I''ll be 80 on crutches at the Victoria''s Secret fashion show hopping down the runway, groaning for my grandkids to help me down!" she told Fox News.

The 35-year-old German beauty has recently been chosen as the new face of the Victoria''s Secret Perfect One bra and admits even though she made many fashion mistakes in the past, she feels sexier than ever, reports China Daily.

"I''ve done things like wearing a sexy dress with granny pants underneath or bloomers with my tight jeans instead of a G-string," she said.

"So I''ve learned feeling sexy is like an onion - the layering, not the scent!" she added.

Klum also revealed that motherhood has made it difficult to stay in shape and she has to follow a sensible diet and exercise regime.

"The only advantage after having children is having a bigger smile on my face. But as far as my body goes, there was definitely more disadvantages. I really have to eat better and work out more now," she added. (ANI)
