Together with Bristolian Marina Wingrove the former hospitality worker joined the Channel 4 Program of 2016.
Her death was confirmed in a statement made on Monday in the name of Mary’s family by Channel 4 and Lambert Studio.
The statement added, “We are deeply saddened to tell you Mary Cook, star of Gogglebox, was gone to hospital with her family this weekend at the age of 92.
“Mary who worked in the hospitalité industry was married and widowed twice.” “Mary, beloved Mother, Grandma, Grandma and lovely friend to many.
Mary and Marina became friends in a retiree village more than ten years ago before being invited to join Gogglebox.
The combo “was favoured with instant fans because of their funny, often cheeky moments,” the statement continued.
“The whole Gogglebox family, cast and crew will miss Mary dearly.
“Mary’s family, friends and Marina are our love and thoughts. At this unfortunate time, the family begged for privacy.”
According to the retirement home from the St Monica Trust, which housed Cook and Wingrove, a Gogglebox researcher uncovered it on a trip to Asda.
Mary remarked on the website, “I’m going shopping so I asked her if she’s going to wait for us.
“They came up to Marina’s flat, they held cards and we had to talk about them.”
Because of the epidemic, the couple were momentarily absent from the programme, but returned in the May programme finale.
