Kirsty makes the shocking false claim against Tyrone (Alan Halsall) next week, in the dramatic aftermath of the pair's wedding.
Whether the ceremony actually goes ahead remains a closely-guarded secret, but either way, the truth comes out and Kirsty is furious when she realises that Tyrone only ever wanted to marry her to secure parental rights over baby Ruby.
During a major row at their family home, violent Kirsty goes to hit Tyrone at the top of the stairs but loses her footing and falls.
Badly injured, Kirsty is rushed to hospital but then uses the situation to her advantage, claiming that Tyrone is an abusive partner.
Gumede told itv.com: "She is angry and desperate and she sees this as the only way she can get revenge on Tyrone and keep Ruby. She is an ex-policewoman - she knows what to do to use the system to her advantage and sound credible.
"The whole stalking situation with Fiz has put her on a good footing with the residents, and also there have been occasions where people saw Tyrone shouting at her. She fell in the back yard once.
"It is all stacking up against him and she is manipulating it to her advantage - she is a very clever woman."
Asked whether Kirsty would be prepared to see Tyrone sent to prison based on her false allegations, Gumede replied: "As this story develops, she certainly seems determined to make him suffer and once she has started telling the lies, she seems to have no desire at all to come clean and clear Tyrone's name."
