But their music video is not the only thing Fifth Harmony has to celebrate.

Recently, Radio Disney is relaunching their series "Next Big Thing" with a new format, and Fifth Harmony will be the first act to be named on the program.

"Radio Disney is proud to be recognized as a first home for many of today's popular young artists, including Selena Gomez, Cher Lloyd, Justin Bieber, Taylor Swift and Austin Mahone," says VP Programming of Radio Disney Phil Guerini according to The Hollywood Reporter.

"This exciting evolution of 'N.B.T.' elevates our commitment to being the first to introduce our audience to tomorrow's next big music stars. And we are honored to be joining forces with the industry legend L.A. Reid, Epic Records and Syco Entertainment to introduce Fifth Harmony as the initial act to launch our new format."

Congratulation to these girls, as all their hard work following "The X Factor" USA seems to be paying off!
