The actress - who plays Weatherfield's Becky McDonald - gave the strongest indication yet that a Corrie musical is on the cards in a TV interview this morning.
Show bosses recently released a CD titled Rogues, Angels, Heroes and Fools, containing ten original songs and billed as an "epic musical journey through 50 years of Corrie history".
Kelly, Kym Marsh, Rachel Leskovac, Bill Roache and Kevin Kennedy were among the cast members past and present who recorded contributions to the project.
Speaking on Lorraine today, Kelly explained: "I think you can really tell when you listen to the whole album that it is the soundtrack of a musical that is very much in the pipeline for next year, that ITV Studios are working on with Trisha Ward, who is the writer of the musical. You can really tell that actually.
"[The CD] is brilliant - there's 23 of us in it. We all popped up to Blueprint Studios and a few of us to Abbey Road Studios to record this, while we were practicing for the live [episode] and the 50th!"
A Coronation Street musical has been rumoured for some time, but the project remains unconfirmed at this stage.
