The actress's mischievous character Ella Hart is expected to bow out on screen later this year after her ongoing toyboy storyline reaches a climax.
Viewers have recently seen Ella seduce young farmer Adam Barton, despite the fact that he is dating her daughter Mia. A fiery showdown has been tipped to take place at Home Farm once the truth is revealed.
However, The People reports that Emmerdale's new series producer Stuart Blackburn recently told Wicks that her current contract will not be renewed.
In a statement confirming her forthcoming departure, Wicks told the newspaper: "I have had a wonderful time and am very much looking forward to filming the dramatic story."
Meanwhile, Blackburn said: "Unfortunately some of the strongest drama dictates the exit of characters."
Today's news follows the previous announcements that Wicks's screen relatives Sapphire Elia (Mia) and Frank Kelly (Dermot) are also leaving Emmerdale.
Other cast members due to depart screens in the coming months include Suzanne Shaw (Eve Jenson), Kirsty-Leigh Porter (Roz Fielding) and Kelsey-Beth Crossley (Scarlett Nicholls).
