Announced by co-creator James Corden in a tweet, he wrote, 'Ruth Jones and I have been keeping this secret for a while... We’re excited to share it with you. See you on Christmas Day', along with a photo of a script.
James, who played Smithy on the show, and Ruth, who played Nessa, will both be returning along with the main cast: Mathew Horne and Joanna Page as Gavin and Stacey, Rob Brydon as Uncle Bryn, Larry Lamb as Mick, Melanie Walters as Gwen and Alison Steadman as Pam.
However, after the ending of the show, it was rumoured that Mathew and James had fallen out, despite the fact that they'd been such good friends whilst working on the show together.
Thankfully, Mathew has now revealed that no-one needs to worry about the state of their relationship, saying in an interview with the BBC that the pair just slipped back into their old ways.
When asked about "healing the rift", Mathew confirmed, "It's a relief for me and James that we didn’t need to do anything. There’s also some sections [in the script] where it says ‘Smithy and Gavlar riff on this’ and that so that’s going to be quite exciting for me and James to have some fun."
He was also able to tease some details about what might happen in the special, saying, "There’s very, very little I can give away - suffice to say he's a little bit tired... and he’s a dad with an almost grown up child.
"I think the audience will be pleasantly surprised and warmed by what they see ... I have every confidence people are going to really like it."
The main actors have now opened up about the show returning, with Rob Brydon - AKA Uncle Bryn - taking to Twitter to excitedly retweet James' original announcement, adding his own comment, 'SURPRISE!!! SURPRISE!!! SURPRISE!!! SURPRISE!!! SURPRISE!!! SURPRISE!!! SURPRISE!!!!!!!!'
Larry Lamb, who plays Gavin's father Mick, also appeared on This Morning yesterday to speak about the show, revealing that he actually cried upon reading the script.
"It’s amazing what James and Ruth have managed to do," he gushed. "I’ve finally read the script, it really got me, I read the first little sequence and just found myself crying.
"It was like running into someone major in your life, you’re not bothered what they do, it was so poignant. I was immediately into the feel of the whole thing, it just brought me along.
'It’s all about this melding of people from different elements of British society, the mindset of people who live in Barry Island and mindset of people in Bury, England, that was the strength. That clever thing of bringing them together and mixing them all up."
We can't wait to see it!
