Birds Of A Feather is to return to the small screen for a Christmas special without one of its main stars, Pauline Quirke.
The 61-year-old actress, who shot to fame as Sharon in the classic sitcom, is "stepping back from acting to focus on her 200 nationwide performing arts academies", ITV said.
The much-loved show, which was a huge hit in the 1990s, was revived by ITV in 2014, and last aired in December 2017.
But it will now be back for the first time in three years for a one-off extended Christmas episode.
Quirke's character has escaped to the other side of the world and is stuck on a Covid-cruise while Tracey and Dorien are dealing with lockdown, the broadcaster said in a statement.
"At the end of a 2020 no one could have predicted, we catch up with the inhabitants of our favourite Essex address ... and find big changes in all their lives," ITV said.
Linda Robson (62) and Lesley Joseph (75) will return as Tracey and Dorien, with guest star Les Dennis as Dorien's new flame.
"I'm so excited to be putting Dorien's high heels back on for a Christmas special of Birds," said Joseph.
"It's been three years since viewers last saw us and Dorien's only gone and got herself a new man.
"We all need a laugh right now and I promise this special will deliver the festive goods."
Robson has promised fans a brilliant script with "lots of laughs".
"Trace and Dor have been at loggerheads with each other for months. Will it be a peaceful Christmas in Essex?" she said.
"The script for this special is brilliant, I promise we'll have lots of laughs for fans of the show."
