Kat Moon in new affair storyline
Jessie Wallace will make her EastEnders comeback with a plot that will see her character cheat on husband Alfie Moon, according to reports.
The actress returns to the BBC One soap on Thursday night's show after taking time off following her split from fiance Vince Morse just hours before they were due to get married.
The Sun reported that five of the Square's characters Ray Dixon, Michael Moon and Branning family members Max, Derek and Jack - could be the man Kat has an affair with, but that bosses are keen to keep his identity under wraps.
In the storyline starting next month, the Queen Vic landlady begins the affair after discovering that her feelings for Alfie have faded.
An insider told The Sun: "Kat returns but she soon feels the spark has fizzled out with Alfie.
"She finds it hard to resist when someone else showers her with affection. Kat tries to call off her affair but she finds her mystery lover impossible to resist.
"Viewers will be left guessing who Kat's mystery man is."
In real life, Jessie is reported to be dating Tim Arnold, a former rock singer and godson to her co-star June Brown.
