Helen Fielding has begun work on a third Bridget Jones novel, 13 years after its predecessor.

With a new film and a musical based on the singleton in the pipeline, Fielding turned to the world of texting and Twitter to help her write a new "scenario for Bridget".

"I'm having a lot of fun, and it's very funny and it's making me laugh", she told BBC Radio 4's Woman's Hour.
