Gavin and Stacey stars enjoyed real alcohol on set

The \'Gavin and Stacey\' cast enjoyed real alcohol as they shot a boozy scene for the Christmas special.

The sitcom is making a much-discussed return to TV screens over the festive period and Robert Wilfort - who plays Jason on the show - has revealed co-creator James Corden suggested the cast drink real alcohol as they filmed one particular scene.

Robert shared: "It was just one of the loveliest days I\'ve had on set filming with everyone.

"Towards the end of the last day filming we may have had a real drink in that scene. Because we didn\'t have any lines and we were just enjoying ourselves, we did all have a drink. It was James\'s idea! It was really lovely. It wasn\'t Archers and lemonade!"

Melanie Walters, 56 - who plays Gwen - also relished the scene, which shows Gavin\'s family meeting Stacey\'s family in Wales.

Speaking to the Sunday Mirror newspaper, Melanie recalled: "What with that and all the singing and dancing, there was no effort involved! I think that transfers to the screen."

Alison Steadman would be 'in heaven' if Gavin and Stacey returned

Co-stars Mathew Horne, Joanna Page, Rob Brydon, Alison Steadman and Larry Lamb had already bonded in the pub prior to shooting the scene.

And Mat - who plays Gavin - admitted to having a "ball".

He explained: "Even Rob Brydon came out. Rob is so dull, he never socialises. Alison is always the last one standing. It was such a ball.

"And that comes across on screen. Particularly the pub."
