Friends' stars David Schwimmer and Matt LeBlanc are set to reunite for BBC show 'Episodes'.
Schwimmer, 47, played Ross on the popular sitcom, while LeBlanc, also 47, played Joey.
The pair are set to reunite on 'Episodes', with Schwimmer making a guest appearance on the show.
An on-set spy told The Sun newspaper: "David and Matt shot scenes together earlier this year.
"It will be a great moment for Friends fans to see them reminiscing about the good old days - but they are unlikely to be best of buds on screen."
The 'Friends' cast - which also featured Jennifer Aniston, Courteney Cox, Lisa Kudrow and Matthew Perry - enjoyed a healthy off-screen relationship while they were filming the show, but Schwimmer and LeBlanc formed a particularly strong bond.
Schwimmer, who spends more of his time directing than acting these days, has previously claimed LeBlanc is the actor who's made him laugh the most.
The cast of 'Friends' recently celebrated the 20th anniversary since the start of the iconic show.
And despite the passing of time, they remain in touch with each other.
A source told The Sun newspaper: "They have all stayed in touch and meet up in groups."
