When ex-boyfriend Dennis Rickman, played by Nigel Harman, returns to the Square, he is shocked to discover that Zoe has lied about the reasons behind their split.
Zoe then admits that she slept with Dirty Den to a packed Queen Vic.
"She leaves because she can't stand everyone knowing what she did in order to persuade Dennis not to leave her," an insider told the newspaper. "It is truly gripping stuff and there won't be a dry eye in the house on the night."
Michelle Ryan, who plays Zoe, filmed her final scenes earlier this month. In her final episode, Zoe decides to start a new life in Ibiza.
