Kelly: 'Corrie plot is a big challenge'
The actress's alter ego Becky McDonald will next week tell screen husband Steve (Simon Gregson) that she has lost their first child.
Speaking of the plot's challenging nature, Kelly told the soap's official website: "It's definitely been the hardest thing I've done since I've been here. I think the responsibility to do it well that you feel is huge."
She continued: "I've just got another six scripts - it just goes from bad to worse [for Becky]. I sat and read them last night and wept. It's just awful.
"She can't really put up any barriers about this - it's the worst thing that's ever happened. She goes from being a girl to a woman, I think. I'm just devastated for her as after three and a half years you become attached to your character.
"I'm finding it hard but I'm enjoying the challenge and that's what I love about this job the most."
Earlier this month, it was revealed that Becky will consider adoption after being told that she will never be able to carry a baby to full term.
