Hoping to get more publicity for their celebrity marriage, Robin and Malik plan a belated wedding reception, but Tasha decides to boycott the party since she believes their marriage is a sham and won't support it. At the reception, Derwin and Melanie must face the reality of their complicated relationship after many people mistakenly congratulate Melanie on her pregnancy. Meanwhile, Rick reluctantly introduces Tasha to his overly protective mother (guest star Penny Marshall), causing fireworks to ensue between the two headstrong women.
