Heidi KlumHeidi KlumWe've been well and truly had.

There we were, chomping on celery and carrot sticks in an effort to be model like, and it turns out we're doing it all wrong.

Apparently such virtuous living does not guarantee you a lustful figure.

Not if Heidi Klum is anything to by.

The model revealed that she is rather fond of a certain fast food joint - you might have heard of it...

"McDonald's is everywhere in the US, but not in the town where I'm from in Germany," the New York Daily News quotes her as saying.

"We had to drive to the next city to get it. It was a huge deal to go! I love that weird sauce with the pickle things in it."
