Playing perfectly into our universal obsession with celebrity culture, All Star Mr. & Mrs. delves into the private lives of three high-profile celebrity couples to see who knows their spouse the best. Playing for charity, each of the pairs must face a series of cheeky relationship questions, match responses to rapid-fire scenarios related to their daily life, and take on the dreaded isolation booth, relying solely on how well they think they know their partner's answers. Egos are checked at the door, and high spirits prevail in this laugh-out-loud romp with the rich and famous.
