Marlon says his five-year marriage to his wife, Dedrea, is on the rocks because she has “let herself go,” and he’s ready to leave her if she doesn’t “step it up.” He says that he wants Dedrea to lose 20 pounds, wear more makeup and dress sexier & to look more like his dream woman, Beyoncé — while also cooking, cleaning and caring for their 5-year-old son. Marlon says he puts a lot of effort into his own appearance — which he thinks is “close to perfect” — and he doesn’t understand why his wife doesn’t do the same. Dedrea insists that Marlon’s narcissism is the real problem in their marriage. She says that his many demands for her are unrealistic — and have hurt her self-esteem. Dr. Phil calls on lifestyle and fashion expert Lawrence Zarian, author of the new book Lawrence Zarian’s 10 Commandments for a Perfect Wardrobe, to give Dedrea a look that she can call her own. How will Marlon react? And, can this couple reconnect — and fix their marriage moving forward?
