Wiz Khalifa's mother, name Katie Wimbush-Polk, is taking his ex-wife Amber Rose to court. According to the Washington County Observer-Reporter, Wimbush-Polk filed a defamation suit against Rose after Rose allegedly made a "profanity-laced" phone call that Wimbush-Polk believed to be accusing her of being a negligent parent.

Wimbush-Polk's lawsuit alleges that Rose made a call to a number linked to Wimbush-Polk's account on June 19. That day, one of Wimbush-Polk's friends and former employees, Danesa Lectic, had possession of the phone, and her five-year-old niece answered the call. The lawsuit alleges Rose launched into her tirade as soon as the niece answered the call.

When Lectic was finally able to identify herself, Rose continued to speak, alleging Wimbush-Polk had allowed her own daughter, Dorien, to die and was therefore unfit to care for Sebastian, Rose's son with Khalifa. Dorien, who was Khalifa's sister, died this past February after suffering from complications due to lymphoma.

Wimbush-Polk is accused of making a call to California child services about Rose, which led Wiz's ex to apparently make the call in question. In the complaint, Wimbush-Polk says she "made no such report at or around that time.”

The lawyer for Wiz's mom says Rose's call “impute(d) criminality,” which is something that's “incompatible with her status as a grandmother and her status as a volunteer mentoring at-risk youth,” which, as the Observer-Reporter notes, requires background checks.

In the lawsuit, which was filed on July 3, Khalifa's mother claims Rose's comments were meant to harm her reputation in her community and that they dissuaded people from wanting to interact with her.

Wimbush-Polk is now suing Rose for $50,000 covering including court costs, interest, punitive and other damages. Neither Rose nor Wiz have responded to the suit.
