Katy gave birth to her first child Joseph last December, and the character has been tipped to act as a surrogate for her sister Izzy (Cherylee Houston) and Gary Windass (Mikey North).
Foote admitted that she hated the fake baby bump she was given when her character Katy was pregnant, telling The Sun: "I'm dreading it - I hated my baby bump last time. The pins stick in your sides and it's so heavy."
Alluding to recent speculation that Katy will become pregnant again, she added: "I never thought for a minute I'd be wearing it again so soon."
Foote also explained that her character's boyfriend Chesney Brown (Sam Aston) will not be happy with the surrogacy idea, explaining that "he is upset she didn't talk to him about it first".
She added that Katy "just wants to help" Izzy after she lost the child she was expecting with Gary, but hasn't "thought through the implications" of surrogacy.
