Maxwell shares with the cast that his famous relative is his grandfather, but the clues throughout the house throw the other cast members off. His lie is that his grandfather is a singer and tells the truth about his grandfather's biggest award being a Hollywood Star. With the shark and dinosaur characters imprinted in the wall, viewers thought Maxwell was the grandson of Steven Spielberg, who famously directed "Jaws" and "Jurassic Park," but the surprising final minutes of the premiere episode proved otherwise.
Maxwell spoke about how his grandfather didn't have a cell phone and was hard to get in touch with, often having to go through lawyers to talk to him. When Pepper is chosen as the person to guess another contestant's identity, she puts Maxwell on the spot and is ready to declare him as Spielberg's grandson. Before she's able to guess his identity, Maxwell is disqualified from the competition and eliminated from the house for using a secret cell phone. He is then revealed as Chuck Norris's grandson, which saves Pepper from elimination.
Answer: Maxwell is Chuck Norris's grandson.
