Kirsty's latest feud is expected to intensify in the coming weeks when she discovers that Fiz knows the truth about her violence towards partner Tyrone Dobbs.
According to the Daily Star, an upcoming episode sees Fiz attempt to fix her machine at the factory when it breaks - only to get her hand trapped when Kirsty (Natalie Gumede) switches the power back on.
Fiz (Jennie McAlpine) apparently needs emergency medical attention due to the bloody injury - and soon starts spreading the word that Kirsty harmed her on purpose.
She is quoted as telling Tyrone (Alan Halsall): "Kirsty said she didn't do it and you might believe her, but in your head I don't think you do. What's she going to do next? She injured you and now she's injured me. Who's going to be next, Ruby?"
Reports suggest that Kirsty protests her innocence to police after Fiz makes a formal complaint about her. To Fiz's dismay, her boss Rob Donovan (Marc Baylis) also backs up Kirsty in front of the police officers.
Rob says: "Where Fiz gets this idea that Kirsty's got it in for her, God only knows."
Coronation Street viewers will see whether Kirsty gets away with her latest stunt when the scenes air later this year.
