Fergie has gone from a size 8 to a size 12

The trend for super skinny celebrities may be dying as another famous face, The Black Eyed Peas' Fergie, has admitted to putting on weight.

Look revealed that the singer piled on almost a stone for her role in new film Nine. She went from 7st 10lb and a size 8 to 8st 9lb and a size 12 for her part as prostitute Saraghina in the musical.

Fergie admits that the weight has gone on her boobs instead of her bum.

In order to put on weight she swapped her regular diet of egg white omelettes, soy protein burgers and rice crackers for fat laden pizzas, chips and fry ups.

Fergie even turned to traditional British foods in her mission to gain weight while she filmed in London.

"I love British food," she said.

"I was told to gain weight for the film so I've been eating fish and chips and everything fried!"

However Fergie is determined to shed all the extra weight in time for her wedding to Josh Duhamel next year.
