The 41-year-old actress, who plays Donna, the wife of Kevin James wife, has confirmed her departure from the series, reported Deadline.
The decision is not about Hayes as the creators have revealed that the show is headed in a new direction in the new season.
"True, I've been let go from the show. Very sad, I had a great experience season 1. Thank you for all the support from our wonderful fans," the actress confirmed in Twitter.
The news comes after Leah Remini was added as a series regular to the show, who will reprise her role as the tough, wise-cracking undercover police woman Vanessa Cellucci.
