Soap bosses are keeping tight-lipped over Nicola's departure, however, in the coming weeks, Nicola and husband Jimmy King are set to run into a spot of bother.
An upcoming storyline sees Nicola being questioned by police when failing to return Priya's baby Amba after offering to take her out for a walk.
Nicola's exit follows on from pregnant co-star Emma Atkins, who bowed out of the soap as Charity Macey last month to go on maternity leave.
