One mother has a twisted sense of love in the upcoming Lifetime movie Mommy Meanest, which will premiere on May 11. TV Insider is exclusively debuting a first-look trailer of Lisa Rinna in her most villainous role to date. The Real Housewives of Beverly Hills alum plays the divorced Madelyn, who is raising her teenage daughter, Mia (Briana Skye). The mother and daughter have always had a tight bond, but when Mia starts spending more time with her boyfriend and prepares to leave for college, Madelyn starts to panic. Their relationship takes a dark turn from there. Mia begins receiving a barrage of degrading texts, and the trailer reveals that the cruel cyberbully is none other than her mother. However, Madelyn pretends to be a protective mom and acts like she wants to find the perpetrator. “You can’t let one crazy person define who you are,” Madelyn tells her daughter.
