Rival Tracy will allegedly miscarry her unborn child before provoking Becky into attacking her. Steve (Simon Gregson) wrongly blames Becky for Tracy's miscarriage and states that he wants her out of his life for good, adding that he'll never forgive her.

"We are all sad to see Kate leave as she has been one of the biggest and most talented stars," an insider told the News of the World.

"But we understand her decision - and [producer] Phil [Collinson] feels delighted to give her a typically feisty exit storyline."

The storyline begins when Steve breaks up with Becky and gets with Tracy, the mother of his daughter Amy. Tracy (Kate Ford) hatches a plot to blame Becky for her miscarriage after discovering that she had a one-night stand with Steve.

Kelly's final scenes will be aired in early 2012. The door will be left open for her return.
