Heidi KlumHeidi Klum on the catwalkYou've got to be fairly confident to strut down the catwalk in a pair of undies.

After all, no one likes to display their wobbles and dimples to the world.

But if you're a supermodel it's pretty much taken for granted that you have a body moulded to perfection.

However, there's still a certain amount of pressure, as you never know when a smidgeon of cellulite might appear.

Now, imagine all that expectation and just add to it the simple factor of recently giving birth... as Heidi Klum has done.

The stunning model, who gave birth in mid-September to a son, clearly hasn't sat on her bottom and rested easy.

Instead, she's snapped herself back into shape in record time, so that she could make her usual appearance on the Victoria's Secret catwalk show.

And boy, did she look good.

Even her hubby Seal was involved in the event - taking to the runway to sing to his flat-stomached wife in her big fluffy white wings.
