Speaking to Digital Spy at last night's TV Choice Awards, Gumede teased that although the Weatherfield villain's feud with Tina (Michelle Keegan) is "far from over", she could soon find herself at war with Jenny McAlpine's character too.
"There's definitely more to come with Kirsty and Tina, but I think perhaps you should look out a little bit more for Kirsty and Fiz," she said. "That might be the next thing to watch."
Gumede added that becoming parents will only quell Kirsty's issues with Tyrone (Alan Halsall) for a short while.
"She's very in love with her daughter, but I don't think it tames her," she said.
"I think there's a bit of a false dawn with Kirsty and Tyrone for a short time, where they think everything may be okay, but ultimately the problems that she has are still underneath and they'll come to the fore."
