Why isnt debby ryan as famous as demi lovato or miley cyrus?

Finally a question of her! :D Well maybe cause she just started in January and because she hadn't singed.Next week on TSloD she sings Country Girl!I know she'll be as famous as them one day.And maybe cause Demi was with the Jonas Brothers and Miley's dad is famous.Debby is a sweet,pretty,nice,down to earth person.She hates cussing and I think she'll be a huge star some day.EDIT:In about a year or so,she'll be a huge star.Tours,millions of fans.
