Jennifer Aniston is being "slowly convinced" into a Friends reunion next year.

The We're the Millers actress has enjoyed a huge movie career since the sitcom ended in 2004, but producers are keen for her to reunite with castmates Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer in 2014.

"Since the show ended in 2004 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," a source said.

Courteney - who played Monica Geller, opposite Jennifer's Rachel Green - has been helping to pave the way for the reunion as she and Jennifer have remained close since shooting on Friends wrapped. "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 passed at all," the source added.

Whether the reunion will take shape as a special episode or another project is yet to be decided.
