Last month, it was revealed that Katy will develop an attraction to bad boy Ryan Connor in upcoming episodes, jeopardising her stable family life with Chesney and their baby son Joseph.
While it's unclear how far things will go between Katy and Ryan, recent scenes shot on location saw the pair sharing secret kisses.
Foote told Daybreak this morning (February 13) that the storyline begins when Katy's friends start teasing her for being 'dull'.
She explained: "It's her friend's 18th birthday, so they're having a party. They all keep taking the mick out of her, saying she's sitting at home and she's boring. She just wants to go out and have fun, and then [Ryan] starts making a bit of a move on her!"
Teasing the upcoming heartbreak ahead for Chesney, the actress continued: "Poor Ches! But poor Katy as well - she has been sat at home with the baby while he's been swanning off to the market. I don't think she means to hurt him, it just happens and it's out of her control, really."
Ryan sees Katy in a new light when he agrees to DJ at her friend's party. He then manages to get Katy a job at the kebab shop, where they grow even closer.
Sol Heras, who plays Ryan, said: "He's never really noticed Katy before, and then he sees her dolled up rather than being a stay-at-home mother. It grabs his attention and it goes from there."
Coronation Street continues tonight (February 13) at 7.30pm on ITV.
