A source told: “Since the show ended it’s been rare for all six of them to appear in public together.

“But with next year’s 20th anniversary [of the show’s launch] it will be unavoidable for them to do something together. It’s the perfect excuse to talk seriously about a new project.

“It’s no secret the whole project will be pinned on Jennifer, who’s incredibly busy with her movie career. But she’s been slowly convinced that a reunion could be a good thing.”

Courteney, who played Monica Geller with Jennifer’s Rachel Green, is apparently doing her bit to persuade her friend round.

The source added: “Courteney has been telling Jennifer that she and Matthew Perry have still got that amazing chemistry after shooting just a few scenes with him guest starring on her TV show ‘Cougar Town’

“It was as though no time has pᴀssed at all.”
