Renee Zellweger has a great idea for a third Bridget Jones's Diary movie, and will play the singleton on the big screen again - as long as she doesn't have to pile on the weight. The actress has padded out to play Helen Fielding's literary heroine in two movies to date, winning over cinema audiences and critics alike with her portrayal of the unlucky-in-love Brit. It has been four years since the last film Bridget Jones: The Edge of Reason - but Zellweger hasn't ruled out a return. She says, "If it works into my life and it's worthwhile and interesting. It depends on there being another book, of course. I would love to read how she's been. Actually, I would love her to go to L.A. and have a baby." But she says of the weight issue: "I had a panic attack with all the specialists talking about how bad this is for you long-term, putting on that much weight in short periods of time. The health professionals were warning me about not continuing the project any further. "(It was) absolutely horrible (losing the weight). The first lap around the track, I felt like I had a small toddler attached to my back."
