Michelle Williams describes how she bulked up for new movie "Blue Valentine:"

"You have to see the movie. I'm nude in some love scenes. It's a big difference from my look now because I had to gain 15 pounds for the part. I finally lost those when I stopped eating ice cream after breakfast, lunch and dinner."

The producers of Ryan Gosling and Williams' controversial new film recently won their fight to land the movie a softer rating.
 
Producers Harvey and Bob Weinstein fought the NC-17 rating and they have won their battle - the film will be released as an R with all its scenes intact. The new ruling now means the movie could be released to more theatres.
