RUTH Jones has leaked 'death spoilers' of Gavin and Stacey's last ever episode this Christmas.
The actress, 57, is adored by millions of fans for her role as Nessa Jenkins in the hit BBC sitcom, starring alongside James Corden.
The Sun previously revealed how the two stars would reunite with the Gavin and Stacey cast for one final time.
Other stars Matthew Horne and Joanna Page in the titular roles along with an ensemble cast including Rob Brydon, Alison Steadman, Larry Lamb and Julia Davis.
And now Ruth - who is currently starring in Sister Act - has dropped a big 'spoiler' about what happens in the finale of the show.

She told the Wondery podcast Brydon & podcast: "A couple of people at the stage door, say 'What’s going to happen, is Smithy going to say yes?'
"And I go to them, 'Do you seriously want me to tell you what’s going to happen in the Christmas Special?' And they go 'yes!'. And I go 'but you don’t, because what happens on Christmas Day when you come to watch it, you’ll know what’s going to happen.' And they go, 'please tell me'.
"So, I go (jokingly) 'there’s going to be helicopter crash, most of the cast are going to get killed', and I just make stuff up!"
BBC bosses will be keeping the plot of this Christmas' last episode under lock and key, but fans are eager to learn what happens next after being left on a cliffhanger in 2019.
Nessa finally popped the question to Smithy and asked him to marry her, but viewers didn't get to see his answer.
Meanwhile, Joanna Page has confirmed this will be her final outing in the role of Stacey after 17 years.
She previously said it would “100 per cent” be the end, dashing hopes of anymore Christmas specials in the future.
