Gogglebox's Shirley Griffiths revealed her husband Dave's job away from the show on Friday night.
The TV personality couldn't resist teasing her partner, telling him "he's in the wrong job" as they watched the latest offerings on the telly.
Fans discovered Dave works as a cleaner in a factory, as Shirley joked: "If you got anything out of that, right, then you're in the wrong job cleaning toilets."
The couple, from Caerphilly in South Wales, have been married for 40 years and joined the series in 2015 after being spotted by a casting agent.
While Dave works as a cleaner, Shirley works in retail.
The cast of Channel 4 boast a whole range of backgrounds and occupations.
Tom Malone is a lorry driver, while his wife Julie is a receptionist in Manchester. Ellie, from Leeds, is a hairdresser while her younger sister Izzi is a mum-of-two.
In the Siddiqui family, who hail from Derby, Umar works in the NHS as a Biomedical Scientist in Microbiology while brother Baasit is a secondary school teacher.
Meanwhile, Giles and his wife Mary Killen are very private when not gracing Channel 4 screens, with little known about their lives away from their living room.
Giles, who contributes to online magazine The Oldie, met Mary when he was 21 while studying at Wimbledon Art School when she was a model.
Mary has been the author of a number of books, including 2012's How the Queen Can Make You Happy.
However, it is known that Giles retired at an incredibly early age and has a rarely-mentioned second job.
While watching a documentary on coronavirus in the 2020 season of the show, Giles said: “Just as I'm starting to enjoy my retirement,” before Mary quickly shot back: “What retirement? You haven't worked first. You retired at 21, so now you can start working – do it in reverse.”
When he's not discussing the week's telly, Giles is working as an artist and has his own artist website, where he explains what his influences are.
On the site, Giles says: “I like the contemplative aspect — sitting for several days in a room, watching the light change.
“There are as many changes as with a landscape. I always work in oils as they give more depth. The finished painting should offer an insight into the painter as well as the subject.”
His artwork includes beautiful paintings of homes and landscapes, with some framed prints selling for up to £250.
