Betty Driver, who played the role of Betty for 42 years, passed away in October at the age of 91 following a period of ill health. Show chiefs are now working on a fitting exit for her alter ego.
Coronation Street's producer Phil Collinson told the Daily Star that the scenes will air in three months' time - with a surprise in store for viewers.
Collinson commented: "Betty's funeral will be shown in April and the scenes will be a treat for fans as they will be a celebration of what the Street does best.
"We will be paying tribute to Betty, but behind the scenes will be the revelation of a secret she has kept hidden. I cannot tell you what it is, but it's a secret that Betty has taken to the grave with her and I can promise you that fans will be surprised.
"There is no love child or anything like that. The secret has something to do with the show's history but I am saying no more."
The newspaper also suggests that there are no plans to bring back former characters for the funeral episode.
