After taking a much deserved break and somewhat scaling back from the musical spotlight, Justin Bieber is back in action as we near the close of the Summer. Taking a slight chance musically, Justin Bieber unleashed his brand new single, ‘What Do You Mean’, just a few days ago. Taking the single to No. 1 on the iTunes charts, the pressure was back on for Justin Bieber to deliver a decent live showing for ‘What Do You Mean’ to keep the momentum going. With an additional treat, Justin opened the performance with Skrillex and Diplo collaboration, ‘Where Are U Now’. Check out Justin’s ‘What Do You Mean’ performance, below.
