Michelle is ripping social media users who question every detail of her life, including her marriage to Memphis-based dentist Dr. Kastan Sims, which apparently doesn't include a prenuptial agreement. On April 27, the Real Housewives of Atlanta star took to X to tell haters, quite literally, to "Shut the f**** up," after a clip from an upcoming episode of RHOA, shared by media personality Kempire that same day, showed her telling the ladies she didn't ask Dr. Sims to sign a prenup before they wed in 2025.
