Last month, show producer Phil Collinson told Digital Spy that the feisty character will feature in a big storyline beginning this Christmas, teasing that the plot will involve "a dark secret that could blow the Platts apart".
Lane has now told the Daily Star of her alter ego's future: "I can't say much, but viewers will see Kylie is trying to up her game in the world.
"You'll see some heart-wrenching scenes. She spills out her emotions to Gail, the only mother figure she's ever had."
Lane is thought to be contracted with Coronation Street until next summer, with the possibility of an even longer stint beyond that.
The actress added that she likes to separate herself from Kylie as much as possible, explaining: "I love keeping it like that. I got in a taxi the other day and the driver was like, 'You're not her - she's a right madam!'
"It plays havoc with my wardrobe, though. Sometimes I'm like, 'Ooh, I like that, but it's a bit Kylie-ish'. You constantly have to question yourself."
Lane joined Coronation Street in summer 2010.
