Brandy, 24, and Jacki, 27, say they believe their mother, Kimberly, is leading an X-rated secret sex life, while maintaining the façade of a happy marriage of 29 years to their stepfather. The daughters say they, along with their younger sister, Hannah, have uncovered Internet ads, emails and text messages full of questionable behavior. As a result, Brandy and Jacki won't allow Kimberly around their children anymore. Kimberly says her daughters are stirring up drama with half-truths and misinformation, and they need to butt out of her business. Dr. Phil looks at Brandy and Jacki's "evidence" and has some tough questions for Kimberly about her behavior. Can he get to the truth — and help put this family back together?
