James – who stepped down as host of US talk show The Late, Late Show last year – wrote in a separate Instagram post: “Some news… It’s official!!! We have finished writing the last ever episode of Gavin and Stacey. See you on Christmas Day.”
Back in February, Deadline was the first to report that a brand new reunion special for the Bafta-winning sitcom would be airing on the BBC over the festive period.
The US media outlet claimed that the “majority of the main cast” will come together over the summer to film a new one-off episode, which would once again be written by James and Ruth, who also star as fan-favourite characters Smithy and Nessa.
At the time, the BBC declined to comment when contacted by HuffPost UK.
However, Ruth appeared to pour old water on these reports, when she claimed (in what we now know to be a red herring): “It’s, sadly, a rumour. I don’t know what to say. All I can say is, if there was something to say, on that front, James [Corden] and I would happily announce it. We would. But some random journalist who’s decided to write this story – I’m lost for words.”
Speculation about whether another Gavin & Stacey Christmas special could be on the cards has been rife ever since 18 million of us tuned in to watch as Nessa got down on one knee in 2019′s festive episode.
