"Only Fools and Horses" stars Tessa Peake-Jones and Gwyneth Strong are to reunite on TV for the first time in 15 years.
The pair - who played Raquel Turner and Cassandra Trotter in the long running BBC sitcom - will appear on "Loose Women" together next week as part of the programme's special "retro week" after previously starring alongside one another in final "Only Fools" episode "Sleepless in Peckham", which aired on Christmas Day 2013.
A source said: "It will be a must-watch for Only Fools fans."
As well as the "Only Fools" pair, "One Foot in the Grave" legends Richard Wilson and Annette Crosbie - who played bickering couple Victor and Margaret Meldrew in the BBC sitcom - will also reunite on "Loose Women" as part of the week's special eps.
Editor Sally Shelford told the Daily Mirror newspaper: "Each show will be filled with nostalgia."
Tessa played the significant other of Derek "Del Boy" Trotter - portrayed by Sir David Jason - in "Only Fools", while Gwyneth starred as Rodney Trotter's (Nicholas Lyndhurst) wife.
But the quartet look unlikely to ever reunite together as the sitcom's characters for a new episode, with both David and Nicholas ruling out a reunion following the death of creator John Sullivan, who died aged 64 in 2011.
Nicholas previously said: "We can't do "Fools and Horses" again as the writers are not there. It will never happen. It ended on a high."
David added: "When we did "Fools and Horses" we just had a writer who just wrote and that was his craft and he handed it onto us. We were very fortunate that we were doing a TV show that was written by such a talented man. Now everybody wants instant success, an instant winner and you can't have an instant winner."
John Challis - who recently appeared on "Loose Women" - and Sue Holderness also appeared in "Only Fools" as couple Boycie and Marlene.
