Lucy Anne Scott, 14 years old. Ally Brooke Hernandez, 21 years old Normani Kordei Hamilton, 18 years old Lauren Michelle Jauregui, 18 years old Karla Camila Cabello 17 years old Dinah Jane Hansen, 17 years old All these girls live together...in one house. Most people would think they argue some, they are wrong. These girls argue ALL THE TIME. Ally, Normani, Lauren, Camila, and Dinah adopted Lucy as a sister. Biggest mistake of their lives. All they do is argue with Lucy about the littlest things. It's 5 against 1, will Lucy ever win?
