Zellweger gets her plump on

Renee Zellweger will begin filming the third installment of Bridget Jones at the end of the year. Time for pizza and skittles for breakfast.

"The story will likely focus on 40-ish Bridget's desire to have a baby before time runs out."

Renee gained 30 lbs. for the last two films. She told the Daily Mail, "Can I just tell you my body is whacked by the time we finish one of those? It doesn't know what has happened because it thinks there's supposed to be a baby and there's no christening."

Renee said overeating was fun at first, "For two days it's bliss...Then after a week your glucose levels are going crazy. You're up and down and all over the place. It doesn't feel good, and no one wants to hear that, but it's the truth."
