The actress is no stranger to writing box office hits having penned and starred in 'Nanny McPhee' and she also won an Oscar for her big screen adaption of 'Sense And Sensibility'.
Now film bosses at Working Title Films have recruited her in to rewrite the first draft of 'Bridget Jones' Baby', which 'Bridget' creator Helen Fielding wrote with 'One Day' author, David Nicholls.
A source told The Sun: “Trying to get a third film into production has been a nightmare.
“The cast didn’t like the script and they’ve now got Emma involved in the hope she can add her British charm.”
Last week, Hugh Grant, who starred in the first two 'Bridget' films, confirmed he would not be returning for the third instalment.
Hugh starred as love interest Daniel Cleaver in the film franchise, but hinted that he wasn't impressed with the new script.
He told the Midlands’ Free Radio: “I decided not to do it. But I think they’re going to go ahead and do it without Daniel.
“The book’s excellent, by the way, but the script is completely different - well, the script as I last saw it a few years ago.”
The third film will differ greatly from the book ‘Mad About The Boy’, which sees a widowed Bridget raising her two young children as a single mother. The film, on the other hand, will reportedly spare the life of Colin Firth’s Mark Darcy character, and instead focus on Bridget’s desire to become a mother in her early forties.
It is also unclear if the film's lead actress, Reneé Zellweger would be returning after author Helen Fielding admitted she had lost touch with her after the release of the last Bridget Jones film, ‘The Edge of Reason’ a decade ago.
