Anne Hathaway had to endure a gruelling diet to slim down for her role in The Devil Wears Prada - insisting she and co-star Emily Blunt would "cry because they were so hungry".

Hathaway plays a journalist who lands her first job on a high profile fashion magazine - and her character is forced to slim down to fit in with her image-obsessed colleagues.

And the actress insists that although she is naturally thin, she still had a lot of weight to lose - and the constant dieting was a real struggle.

She says, "I was thin for my height. I was basically stuck with fruit, vegetables and fish. I wouldn't recommend that.

"Emily Blunt and I would clutch at each other and cry because we were so hungry."
