Nomvete, who played Mandy Kamara, announced the news on her Twitter page today (July 31) after a fan congratulated her for reaching the one-year mark on the show.
Her on-screen daughter Krissi Bohn (Jenna) also discussed the news, tweeting: "I miss you @Pamelanomvete. Can't believe it was only a year ago we met!"
Mandy is expected to bow out on screen next month following some troubled times for her relationship with Lloyd Mullaney (Craig Charles).
A Coronation Street spokesperson told Digital Spy: "Pamela's departure from the show is storyline-led and there's nothing to say that Mandy won't return to the Street in the future with familial ties remaining in Weatherfield."
Mandy was introduced to the soap last year as an old flame of Lloyd's. As Lloyd tried to reconnect with Mandy, he was later shocked to discover that he was the father of her grown-up daughter Jenna.
Following the bombshell, Mandy moved in with Lloyd and secured a job as the Rovers Return's new chef.
