Viewers were left stunned on Saturday night as Gavin and Stacey appeared on their screens during the finale of Nessa Strictly Come Dancing.
Actress Ruth Jones gave her character a catchphrase, “What’s going on?” Before the first clips of Gavin and Stacey’s final episode were shown.
The final episode is due to air on BBC One on Christmas Day. The last fans saw of Nessa and Smithy, played by James Corden, was in the 2019 Christmas special, where Nessa got down on one knee and asked Smithy to marry him.
