Teen pop duo Jonnie and Brookie of Phoenix, Ariz., have been named Radio Disney’s "Next Big Thing" via a poll that tabulated nearly nine million votes on RadioDisney.com and via texts to Radio Disney from listener's mobile devices, it was announced on air by Radio Disney's Ernie D. Radio Disney’s N.B.T., a recurring on-air and online programming feature, puts the spotlight on young recording artists and allows them to get their music heard on a national level. Since its November debut, Radio Disney’s N.B.T. introduced 11 unsigned acts and invited its kid and family audience to look, listen and vote for their favorite new artist online or via text.

Jonnie and Brookie, who are sisters age 16 and 14, respectively, will perform in concert at an exclusive Radio Disney event to be announced shortly. They narrowly edged out three other frontrunners -- AllStar, Bre Morgan and fellow Gibson endorsees Comic Book Heroes.
