Mum's the word: HeidiThere's an old saying that you can never be too rich or too thin.

And it seems Heidi Klum might have been taking this silly piece of advice to heart.

The supermodel has come under fierce criticism of encouraging weight loss after a comment she made on German TV.

Heidi, who was on the judging panel of Germany's Next Top Model, told an eight-stone girl: "Top designers need only girls with dream figures."

The comment has not gone done well in Germany - so much so that the show might be axed after a barrage of complaints from the public.

Eating disorder expert Dr Ulrich Rau told The Sun newspaper: "I consider such a TV show to be very dangerous.

"Most of these young girls who want to be models are already too thin."

Heidi recently faced her own weight battle as she fought to shed the pounds she put on whilst pregnant with her second child.

She was at the Emmys in a slinky gown five days after the birth, and back on the catwalk in less than two months.
