Becky was recently left devastated when scheming Tracy Barlow (Kate Ford) accused her of causing her miscarriage by pushing her down a set of stairs.
Viewers are aware that Tracy is lying as she slipped rather than being pushed - and she actually lost her babies the night before. However, Steve (Simon Gregson) has been fooled by Tracy's claims.
Kelly told This Morning today: "Becky's got to clear her name now - that's the thing. She's worked really hard, it's been this lovely redemption story and the Croppers have trained her to be a good woman.
"And now not only has she lost the love of her life, it looks like she might lose her good name - which is what she's worked so hard to achieve. The last couple of weeks, which is all it is now on screen, really is for Becky to prove that she is not the evil person that Tracy is making her out to be."
Kelly also admitted that bowing out from Coronation Street was an emotional experience. She departed the soap in December.
"My last day on set - I actually filmed my final scenes with the Croppers, when she does say goodbye to them," the actress explained. "Myself and Julie [Hesmondhalgh] who plays Hayley - well, she was beside herself! She didn't stop crying in between the takes!
"And then with Simon, it wasn't quite the last scene but it was a very emotional scene. Because we film out of order, I actually filmed my final scenes three weeks before I left. But I'm really looking forward to watching it all, with the rest of the nation!"
Kelly is currently in rehearsals for comedy play She Stoops To Conquer, which begins a run at the National Theatre in London later this month.
