Beyonce KnowlesBeyoncé Knowles has revealed she lost 20 pounds of weight for her role in her latest movie Dreamgirls.

“It was my idea. At the beginning of filming, I was my normal weight.”

“I actually gained a little bit, but then I lost 20 lbs. when I went from young Deena to old Deena.”

“I wanted it to be something more than just make-up and hair. I wanted to see the change.”

“[Director Bill Condon] actually kept telling me to eat, eat, eat for continuity, but I really wanted to go all the way. I was inspired by Tom Hanks.

“He did it all the way in the movie ‘Castaway’, so I said I can do it all the way!”

She didn’t intend to stay thin after filming finished though: “Immediately the next day I ate fried chicken, fried fish, french fries - anything fried and the weight started to come on fast and easy.”

“[Being thin] wasn’t healthy. I didn’t look like me at all in the film which was the point.”

The film is due to be released at the end of the year.
