Christopher Biggins is worried his friend Dame Barbara Windsor has forgotten she's famous.
The 69-year-old star is so proud of the legendary actress for opening up about her battle with Alzheimer's disease - a chronic neurodegenerative condition that usually starts slowly and worsens over time - because she's already starting to question why people ask her for selfies.
Speaking to the Daily Mirror newspaper, he said: "You go out with her and people want to chat, get an autograph and have a selfie... The only problem is that in the future, and sometimes already I think, she won't understand why.
"She may forget her whole glorious career, why she is so famous... But it if that's the case then it's down to us, her dear friends to help her amazing husband, Scott, to remind her."
Barbara's husband Scott revealed the 80-year-old star's battle with the condition yesterday (10.05.18) and has said that he hopes them coming forward will help other sufferers.
He said: "I hope speaking out will help other families dealing with loved ones who have this cruel disease. Secondly, I want the public to know because they are naturally very drawn to Barbara and she loves talking to them.
"So rather than me living in fear she might get confused or upset, they'll know that if her behaviour seems strange, it's due to Alzheimer's and accept it for what it is."
The "Carry On" star has been in a "definite continual confusion" since she turned 80 last August, and while she enjoys going out for walks, Scott - who has been married to the actress for 18 years - admitted she feels "a kind of shame" about the diagnosis.
Barbara has now retired from charity work as well as acting as a result of the disease.
