The actress, 53, is said to be returning to her famed role as the lovable bachelorette for a fourth film in the popular franchise.
It was reported on Friday by The Sun that producers have been ‘secretly’ working on the project.
Bridget was last on the big screen six years ago when the film Bridget Jones’ Baby saw her pregnant and trying to work out who the father was.
The rumoured upcoming film is understood to have been co-written by creator Helen Fielding, 64, and will see Renée tell the story of motherhood with her boy.
A source said: ‘There have been few more successful or more popular rom-coms than Bridget Jones over the last couple of decades, but everyone thought this one was done for good.

‘However the producers always knew there was a huge market for another sequel when the right story was available, and this feels like the right time to tell it.
‘It will be seven or eight years since the last movie by the time this one hits the big screen, and fans will be desperate to find out what happened. It’s a British classic.’
