No word on an exact air date, but it appears the special will air sometime between 20 Dec and 2 Jan (most likely before Christmas) on BBC1.
Also scheduled to air that week is a “behind-the-scenes” documentary.
More details to come, as they become available.
From the official press release (after the jump):
Gavin & Stacey Christmas Special
It’s Christmas Eve and the Wests join the Shipmans for one of Mick’s famous turkey dinners, as the award-winning Gavin & Stacey comes to BBC One for a special festive episode.
Smithy can’t wait to spend his first Christmas with baby Neil, but doesn’t count on Dave Coaches tagging along and playing happy families with Nessa. Jason and Bryn, meanwhile, have a heart-to-heart about “that” fishing trip and Gavin and Stacey’s revelation to Pam and Smithy doesn’t quite turn out to be the Christmas present they were expecting.
Mick is played by Larry Lamb, Smithy by James Corden, Dave Coaches by Steffan Rhodri, Nessa by Ruth Jones, Jason by Robert Wilford, Bryn by Rob Brydon, Gavin by Mathew Horne, Stacey by Joanna Page and Pam by Alison Steadman. Melanie Walters also stars as Gwen.
