Renee Zellweger won’t be piling on the pounds to reprise her role as overweight diary-keeper Bridget Jones in the latest addition to the popular Bridget Jones’ Diary film franchise — she’ll don a fat suit instead.

The Oscar-winning star has signed on for a third film about the unlucky in love Brit and her quest to become a mother in her 40s. But instead of embarking on a high-fat diet as she did for the 2001 and 2004 films Renee will wear a costume to make her appear larger, The Mirror learned on Tuesday.

“Renee will be wearing a fat suit in the third film as it took her a while to lose the weight last time. She’s also thinking about the effect quickly putting on and then losing 30 pounds has on her body,” a production source reveals.
