'Gavin and Stacey' stars James Corden and Mathew Horne go clubbing as they film Christmas special

They might be in the midst of filming the hotly-anticipated Christmas special of Gavin and Stacey, but that hasn’t stopped co-stars Mathew Horne and James Corden from having plenty of fun in their downtime.

On Sunday 20 July, the close pals were seen dancing the night away by a eagle-eyed fan in Tiger Tiger nightclub in Cardiff.

In the footage - which was first spotted by the Daily Mail - the actor and talk show host both wore casual black tops and jeans, as they sang along to Whitney Houston’s iconic tune I Wanna Dance With Somebody.

In one of the two videos, 40-year-old Horne can be seen in high spirits, as he tops up Corden’s drink before pretending to swig straight from a bottle of vodka.

“Drop it,” he shouts, enthusiastically as the song reaches it’s crescendo.

As expected, the whole Gavin and Stacey gang - which also consists of Ruth Jones and Joanna Page - has enjoyed being back together as the shoot the upcoming episode in Barry, Wales.

Just a few days ago, Corden, 40, took to Twitter to share photos of the foursome, which had been put through FaceApp to make them all look old.

“Filming for the new special is going well,” he wrote alongside the selfies, before joking: “Here’s a first look at the Gavin and Stacey cast 10 years on. Basically nothing’s changed.”

Corden, who created the show with Jones, recently told the Sunday Times Culture magazine that they “just want the new show to be a nostalgic joy-bomb,” which means it will probably avoid addressing controversial topics such as Brexit.

“We owed it to the characters,” he said, when asked why he wanted to return to the hit British sitcom. “We wanted to see if there was something there, and for a while we weren’t sure.

“Then, once there was, my feeling was, life’s too short. Fear is the absolute reason to do it.”
