New Delhi, November 12 : Fergie, who is set to star alongside Nicole Kidman in the musical film 'Nine', has put on 13lbs for her role as a prostitute.
The 'Black Eyed Peas' vocalist, who will be playing Saraghina, said that she deliberately replaced her habitual eating routine with greasy treats to gain those extra pounds, reports China Daily.
She said: "I've actually gained 10lbs! No, really - for the film, 'Nine'. Actually, 13 to be exact. I ate everything! Fish and chips. Everything fried - things I don't normally eat."
However, singer-actress added that she had to shed it off before she tied the knot with fianc Josh Duhamel.
She said: "I have to give the bad food up now! So, yeah - I'm in that phase! Back to diet designs - my food delivery service!
"You can do creative things with food though. You know, turkey isn't fattening - you can do that. A little bit of gravy. Or have a nice big salad!"
