Listen to Justin Bieber on iHeartRadio

Justin Bieber is giving his endorsement to another up-and-coming young singer. 

The pop star made a cameo appearance in the debut video of Madison Beer, a 14-year-old from Long Island, New York who he discovered himself on YouTube. 

Last year, Justin heard Madison  singing a cover of Etta James' "At Last," and posted the video to his Twitter page.  It went viral.   Since then, Madison has been taken under the wing of Justin's manager Scooter Braun.  Madison, who's being called Bieber's new protégée, released her debut single called "Melodies" on Thursday.  

Scooter and Justin are responsible for kickstarting the career of Canadian singer Carly Rae Jepsen.  They've also supported current Billboard 200 topper Ariana Grande by bringing her on Justin's "Believe" tour.
