Olivia Grier. 18 years old, twins with Nash Grier to be exact. Sure she may be Nash's sister but who said she's friends with Cameron Dallas or Matthew Espinosa? Who says she's even known to them? She's a secret sister I guess. None of Nash's friends know about her. They don't even know about her singing and rapping talent. What will happen when Nate Maloley finds Olivia rapping to his song? Will he freak out or will it be love?
