The Real Housewives of Potomac star Michael Darby is taking Candiace Dillard Bassett to court after she claimed he had sexual relations with another man.

During this past season of the hit Bravo series, Dillard Bassett brought up Darby while speaking to his estranged wife, Ashley, telling her, “Your husband likes to leave you and go to a man named [censored]’s house and suck his d**k.”

Though Dillard Bassett didn’t reveal who the man is, she later claimed Darby paid for sex.

TMZ said the real estate mogul sent Dillard Bassett a cease and desist letter earlier this year, stating her allegations are false.

Per legal documents, Darby is now suing the fellow reality star for defamation and is seeking $2 million in damages.

This latest installment continues a long-standing feud between Dillard Bassett and the Darbys.

Though it seemed like Dillard Bassett and Ashley Darby were becoming friends again, this was short-lived.

Ashley seemingly initiated the back-and-forth when she claimed Candiace’s husband, Chris Bassett, flirted with her friend, Deborah, at fellow housewife Karen Huger’s event. It was later revealed that Chris and Deborah’s interaction was strictly casual.

RHOP star Gizelle Bryant later said that Chris made her “uncomfortable,” which didn’t sit well with Candiace.

Darby then insisted that Chris was sending private messages to other women, leading Candiace to clap back at Ashley about her rocky marriage and Michael Darby’s alleged sexual activity.
