The veteran actress shared a photo of a monkey wearing a wig -- widely seen as a pointed reference to Yinka -- and slammed her in a lengthy post on Instagram.
She wrote: "Edochie's family is not a dumping ground for retarded individuals. Person wey no get integrity dey constitute nuisance on the streets of social media. I join all right-thinking men and women, especially May Nation, to call on this mentally deranged individual in America to stop being a nuisance online."
Rita went on to accuse Yinka of spreading shame on the family and described her as a "public bore hole," warning that her antics would no longer be tolerated. She urged Yinka to move on from the family and focus on her own life, even suggesting she "move into the bush and start hunting for another young man" instead of interfering with theirs.
The feud stems from Yinka's past relationship with Linc Edochie, which ended bitterly. Since then, Yinka has repeatedly targeted members of the Edochie family online, prompting strong responses from Rita, who has been vocal in defending May Edochie following Yul Edochie's second marriage.
Fans have reacted in mixed ways, with some applauding Rita for defending her family while others have called for both women to end the public confrontation. Yinka has yet to respond to Rita's latest post.
