Courteney and David together for show

Courteney Cox and David Arquette are back together - to work on a new game show.

The estranged married couple - who announced a trial separation last year - have jointly sold a pilot called 'Identity Crisis' to CBS.

The programme requires contestants to identify celebrities based on a number of clues and is based on a board game.

Courteney and David are acting as executive producers on the show and if the pilot is well received then a full series will be commissioned.

The game show is the third TV project the pair have worked on together, following 'Dirt' and 'Cougar Town' - both of which starred the former 'Friends' actress and were produced by their company Coquette Productions.

Although they have maintained a working relationship and have remained on good terms since their split, David recently admitted he is unsure if he and Courteney will ever reconcile.

The 39-year-old actor - who has a six-year-old daughter Coco with the 46-year-old screen star - said: "I really don't know what's going to happen. It's up in the air. But we really love each other and we're great parents together and we have a business together. We're both figuring out a lot about our lives at the moment and our personalities and what we need to feel more complete."
