"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 script was still said to be "taking shape" in September, when Tim Bevan, the co-chairman of Working Title Films told The Huffington Post that the full cast, including Grant, Renee Zellweger (Bridget Jones) and Colin Firth (Mark Darcy) were expected to reprise their roles.
In 2012 Hugh, who's currently promoting new romcom The Rewrite, admitted that he had a large hand in the makings of the script for second film, Bridget Jones: The Edge of Reason.
At the time, he confessed that he had been "difficult" when it came to moulding Daniel Cleaver for the next part of the story.
"I'm always quite difficult," he said. "But I was really impossible on this one. And there was a lot of coming and going about the script and my part.
"To begin with, I was not convinced that Daniel Cleaver could ever go into television, a medium he despises. But I got my head around that and did a lot of work on just sort of trying to keep the cleverness of Daniel."
Grant, who's famous for his romantic comedy roles in Four Weddings And A Funeral and Music & Lyrics, also said this week that he looked back on many of his famous roles with distaste.
Speaking to The Mirror about The Rewrite, where he plays screenwriter turned teacher, he said: "I have pretty much hated any other film I've ever been in. But I liked this one.
"Nowadays I pretty much turn everything down anyway, because I just feel too old. Certainly for romantic comedy and certainly for showbusiness in general. Occasionally, they wheel me out."
