Following a nine-year hiatus, the hour-long special will revisit the original cast, which also includes Rob Brydon, Larry Lamb and Alison Steadman.
The original series followed Gavin (Mathew Horne), from Essex, England, who strikes up a long-distance relationship with Stacey (Joanna Page), from Barry, Wales after they call each other up for work. Eventually they agree to meet up in person— with their best friends in tow — before quickly falling in love and getting engaged. The show also followed the impact their romance had on their surrounding friends and family.
The series ended with Nessa (Ruth Jones) and Neil “Smithy” Smith (James Corden) reconciled after the latter interrupted her wedding, while Stacey and Gavin learnt that they were expecting their first child.
Watch on Christmas Day 8:30pm on BBC One.
