After 41 years of marriage, Dr. Phil McGraw and his wife, Robin McGraw, are more smitten than ever. So what's the secret to their lasting happiness? "Me saying, 'Yes, dear!'" Phil, 67, joked in an exclusive new interview with Closer Weekly, on newsstands now. Robin, however, begged to differ and insisted that she fell in love with her husband the moment they met. "It was love at first sight — well, maybe at the end of the first night. But I actually knew that first evening I sat and visited with him that he was the one," the 64-year-old said. You know you can always lean on me, love!
