Gogglebox fans and cast members flocked to Twitter to pay tribute to the late star.
Cast members Dave and Shirley wrote: “So sad to hear the passing of Mary.
“She was a lovely funny lady, our thoughts are with Marina and Mary’s family #Gogglebox #MaryCook.”
Addressing Marina’s tribute, Mandy Amory commented on the post: “Bless Marina and bless Mary as that was lovely. And I hope Marina is able to continue with #Gogglebox when she’s ready – although it won’t be the same without Mary.”
