LONDON: Supermodel mum Heidi Klum has stepped down from the catwalk at this year's (09) Victoria's Secret fashion show - opting to host the event instead.

The German beauty is stalwart of the annual lingerie showcase, which sees the world's highest paid and most stunning models take to the runway in skimpy underwear and angel wings.

But rather than force herself back into shape following the birth of her fourth child last month (Oct09), the new mum will play host at the sexy event, according to E! Online.

She recently told the website she was worried about missing the show altogether: "The last time (I gave birth), I had two months, and I don't know if I have that much time this time. It was pushing it the last time. But if I don't make it, I'm sure I'll be very sad."

Klum, who is married to singer Seal, famously toned up in time to strut her stuff at the 2006 Victoria's Secret show - just two months after she gave birth to her third child.

The fashion show will take place on 1 December (09), and features a performance from the Black Eyed Peas.
