Welsh actress Ruth Jones has revealed the Gavin And Stacey finale might not be what viewers are expecting.

Gavin and Stacey, which first aired back in 2007, last appeared on our TV screens on Christmas Day 2019.

The special episode ended on a cliffhanger with Nessa (Ruth Jones) proposing to Smithy (James Corden).

Earlier this year Corden and Jones - who are also the show's co-creators and writers - revealed Gavin and Stacey would be returning for one final episode on Christmas Day (2024).

BBC teases what to expect in Gavin and Stacey finale

The BBC has given fans a little teaser of what to expect from the Gavin and Stacey finale on Christmas Day.

In a synopsis of the finale, the BBC said: "It’s five years since we left Nessa down on one knee declaring her love for Smithy and asking him to marry her. And a lot has happened in those five years."

The broadcaster explained that the 2024 Gavin and Stacey Christmas special will see Gavin and Stacey “looking for new ways to spice up their 17-year marriage”, while Nessa begins a new business venture.

It also sees Rob Brydon as Uncle Bryn getting his Citroen Xsara Picasso ready on Barry Island for a trip to Essex, as his sister-in-law Gwen West has been “behaving most strangely”.

Meanwhile, Neil the Baby is set to start an “apprenticeship with his dad”.

In Billericay, Michael “Mick” Shipman (Larry Lamb) is upsetting his wife Pamela Andrea “Pam” Shipman (Alison Steadman) as she is about to play hostess.

While there will also be continued marital problems for Peter Sutcliffe (Adrian Scarborough) and his wife, Dawn Sutcliffe (Julia Davis).

The BBC added: "Join us on the journey to Barry and Billericay as we catch up with the Shipmans and the Wests for the very last time and maybe find out what exactly did happen on that fishing trip."

Gavin and Stacey finale "might not be what you are expecting"

But Jones, speaking to the Big Issue, said: "I keep telling people this finale might not be what you are expecting.

“And I guarantee we will definitely not be coming back.”

Corden, 46, added: “What people are going to see on Christmas Day is the culmination of a 20-year love story, which hopefully shows, if nothing else, that love is complicated and messy and for everyone.”

James Corden says he "treasures" friendship with Ruth Jones more than Gavin and Stacey

Corden and Jones, 58, also spoke about their friendship outside the show.

“Lots of my friends walked in with a mariachi band playing. Then my wife said, ‘There’s one more person here.’

“Ruth walked into the room and I just burst into tears. I couldn’t believe she was there. It was so special.

“It’s that strange thing, isn’t it? If you haven’t seen someone for a while and they walk in, you’re suddenly aware of what you mean to each other.

“I can’t tell you how we’ve changed. But I know we have changed a lot.”

He added: “I can only speak for myself, but I treasure our friendship more today than I ever have. And I value it even more than the show.”

Corden and Jones also starred opposite one another in TV series Fat Friends, which ran from 2000 to 2005.

After the success of Gavin And Stacey, Jones went on to create and star in Sky One comedy drama Stella, while Corden fronted The Late Late Show on US TV.
