Justin Bieber just earned another career highlight and this time it’s all thanks to his brand new single, ‘What Do You Mean.’ After officially announcing the single over a month ago, Justin enlisted the help of famous celebrity pals to count down the days until the world would hear the new record. Immediately flying to No. 1 on iTunes charts across the globe, Justin wasn’t finished just yet a he dropped the music video after his comeback performance at the VMAs. With everything aligned perfectly for a massive debut on the Billboard Hot 100, Justin gave an additional performance on “The Tonight Show With Jimmy Fallon” to further promote ‘What Do You Mean.’ All the hard work has paid off as Justin has officially debuted at No. 1 on the Billboard Hot 100 with the record. This officially marks Justin’s first No.1 single as his highest peaking record is with his 2012 single, ‘Boyfriend,’ at No. 2. With his album due out in November, Justin is simply just getting started.
