All six Friends actors are in talks for a one-off unscripted reunion show, according to reports in the US.
However it would apparently not involve fully reviving the hit sitcom, which ran from 1994-2004.
HBO Max secured the US rights to all 10 seasons of Friends for $425m (£340m) for its service, which is due to launch in April 2020.
The show will move from Netflix, where it has found a new lease of life with younger audiences, being the second most-watched show in 2018 – according to Nielsen data.
Jennifer Anniston, who played Rachel on the show, recently joined Instagram and attracted almost five million followers in 12 hours after posting a selfie alongside co-stars Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer.
She later cryptically told US talk show host Ellen DeGeneres they were “working on something”.
She said: “We would love for there to be something, but we don’t know what that something is. So we’re just trying.”
While one or two of the stars have worked together on various other projects, including the spin-off series Joey – which saw Schwimmer direct LeBlanc in several episodes – all six have not been seen together publicly since the show finished.
HBO Max has not commented on the reports.
