HEIDI KLUM found an unusual way to satisfy her pregnancy craving for chocolate - by stripping off and being photographed smothered in it.

The supermodel has been working on a photo book called Heidilicious with pal Rankin and said the shot, above, is one of her favourites.

Revealing the snap on US telly, Heidi told host Ellen DeGeneres: "We were doing our normal shoot and afterwards he said, 'Let's do some pictures for the book.' I said, 'I would love to be covered in chocolate.'

"So someone ran out to the store and got, like, I think, seven or eight of those squirty chocolate things and they just squirted it all over me and he took the photo.

"It was yummy... especially when you're pregnant."
