<P> First, Madea confronts Sabrina about abusing Byron's hard - earned money, and that she needs to start respecting him, especially telling her to stop using their child to make his life miserable or she will be dealing with Madea herself or worse . Second, Madea confronts Byron and tells him to get himself a new job in order remain on the right path, because selling drugs again will only lead him to his own demise (a return to prison or an early grave) and Renee will just move on to the next man with a lot of money; Madea also threatens Renee when she attempts to backtalk . Madea also tells both Byron and Sabrina to start working together to take care of their baby, and settle things between them wisely and peacefully . Third, Madea tells everyone that Shirley didn't want her children to know that Kimberly had been raped by an uncle of hers, on her father's side, when she was 12, which resulted in her pregnancy with Byron, and was why she became so hostile and aggressive towards everyone, because she hadn't forgiven the man that raped her . Madea urges Kimberly to forgive her uncle for her own sake; otherwise, he'll continue to have power over her, and she'll never be able to move on or make peace with herself and what he did to her . Kimberly then sorts out her issues with Calvin, feeling that she doesn't know how to begin, and finally hugs him and apologizes while they agree to acquire some professional help . Byron breaks up with Renee, because he just buried his mother while Renee keeps thinking only about herself, and trying to get him to deal drugs again . </P> <P> The film ends with Madea, Mr. Brown, and Cora on The Maury Povich Show to find out if Mr. Brown is in fact Cora's father . Madea insists that he is, but it turns out he's not . This shocks Madea, who runs off - stage, sobbing hysterically . Madea does this mocking the running gag on the Maury Povich Show of how many of the woman, when it is revealed that their old romantic interests are not the real fathers of their child (ren), they run off - stage and sob wildly and hysterically . (Although the DNA tests on the show reveals that Mr. Brown is not Cora's real father, this, however, is non-canon to the rest of the Tyler Perry franchise as Mr. Brown is still portrayed as Cora's father). </P> <Ul> <Li> Tyler Perry as Mabel "Madea" Simmons and Uncle Joe Simmons </Li> <Li> Loretta Devine as Shirley </Li> <Li> Shad "Bow Wow" Moss as Byron </Li> <Li> Tamela Mann as Cora </Li> <Li> Cassi Davis as Betty Ann "Aunt Bam" Murphy </Li> <Li> Lauren London as Renee </Li> <Li> Shannon Kane as Kimberly </Li> <Li> Isaiah Mustafa as Calvin </Li> <Li> Natalie Desselle - Reid as Tammy </Li> <Li> Rodney Perry as Harold </Li> <Li> David Mann as Leroy "Mr. Brown" Brown </Li> <Li> Teyana Taylor as Sabrina </Li> <Li> Philip Anthony - Rodriguez as Dr. Evans </Li> <Li> Chandra Currelley as Sister Laura, the lead singer of the church choir at the funeral who sings, "Heaven Waits For Me ." </Li> <Li> Maury Povich as himself </Li> </Ul> <Li> Tyler Perry as Mabel "Madea" Simmons and Uncle Joe Simmons </Li>
