Ruth Jones is forced to apologise live on BBC Radio 2 as she makes on-air blunder - as Gavin And Stacey fans beg the cast to front the show for good

Ruth Jones was forced to apologise live on BBC Radio 2 after making an on-air blunder while fronting the show alongside James Corden on Monday.

Gavin And Stacey's creators took over as hosts on the breakfast show and were joined by a plethora of cast members ahead of the sitcom's final ever episode.

Fans have hailed the takeover as 'iconic' and have begged the cast to front the show for good.

During the live show, Ruth, 58, who plays Nessa Jenkins, left the cast in stitches as she swore while reciting one of the lines from the series.

Speaking to Alison Steadman, who plays Pam, Ruth said: 'Alison, I remember you were sitting on the beach with the lovely Margaret John and you were both there in your sun hats.

'It was so nice and she had that line when Mick takes his top off and she went "Oh you're a lucky b**** Pam!"

'Am I allowed to say b**** on a radio show? Probably not. Sorry, I apologise!'

James joked: 'I don't think you are. I think we've just been told you're officially not allowed to say that.'

Ruth said: 'I apologise!'

Gavin And Stacey fans declared they wished the stars fronted the show 'every day'. 

During the show James and Ruth revealed secrets about the upcoming finale, shared some of their favourite memories from the series and discussed all things festive.

And fans of Gavin and Stacey were clearly loving the cast's radio work as they rushed to X, formerly known as Twitter, to share their joy as hearing the actors on the airwaves in the morning.

They penned: 'Loving the cast of Gavin and Stacey on @BBCRadio2 this morning. Heading home to the valleys later today, and it’s making me all the more giddy. Tidy!!

'#Gavinandstacey taking over the #BBCRadio2 breakfast show is ICONIC! I love it.'

'Merry Christmas Ruth & James, waking up early this morning just to listen to you guys! I've watched Gavin & Stacey right from the beginning & can't wait to watch the finale'

'The crew of #Gavinandstacey should be on every breakfast show……. Hilarious, and brilliant.'

'Would quite like to wake up to Ruth Jones every morning! #Gavinandstacey #BBCradiotwo A treat I wasn’t expecting.'

James and Ruth were joined by Joanna Page, Mat Horne, Rob Brydon, Alison Steadman, Larry Lamb and Rob Wilfort for the three hour long special. 

The supposed 'last ever' installment will air in a 90-minute special on Christmas Day this year after fans of the show begged for an end to the story. 

It comes after James and Ruth revealed Gavin & Stacey fans will be treated to a lot more Smithy and Nessa in the final episode, musing that their characters' 'messy' relationship is the beating heart of the BBC show.

Appearing on the podcast Table Manners with Jessie and Lennie Ware, the actors and writing partners teased the Christmas special, spilling that fans will find out a lot more about Ruth's character Nessa's past as well as her future with Smithy.

'Nessa has had this unbelievable checkered life and you find out more about that in this special — some really fun bits that we wrote,' James explained. 

He mused that the reason fans have taken Smithy and Nessa to their hearts is because 'on TV or films, you very rarely see people that look like Ruth and I fall in love.'

'You just don't. I'd be dropping off a TV to Hugh Grant in Bridget Jones and Ruth's like working on a newsstand when someone buys a newspaper.' 

 'What I like about the show is that it's so messy and complicated and they just clearly have fantastic sex. I really enjoy that confidence.'

Ruth added though that in the early days, the writers partners were unsure how to pitch the unique relationship, explaining: 

'The first time they had sex was in the very first episode and I think because we didn't quite know what the show was we were probably being quite sitcom about it.'

'We were there, just the two of us, on that road that had meant so much to us and I just, as Ruth, was looking at my dear friend James and when I said 'I loved you with all my heart' I was saying it to you [James],"  Ruth recalled.

Despite the pair now promising the upcoming special actually is the finale, there's been a flurry of fan speculation that there could be more to come.

James is adamant though that this is it, giving an ominous  warning to viewers as she said: 'It can't carry on. When you'll see it, you'll know.'

The pair aren't saying no to working together again with James promising: 'We don't know if we have another idea in us but I can honestly say that if we didn't attempt to try and even explore the idea of writing together then I'd be so disappointed.'
