Fresh off accompanying Floyd Mayweather Jr. as a belt bearer on Saturday, last night during the season finale of NBC's The Voice Justin Bieber gave fans his first live performance of his latest track "Boyfriend." Fitted in a studded jacket and golden high-tops, the 18-year old made his way down light-filled corridor to deliver his performance alongside his back-up dancers. He's continuing to shed his innocent image fans first recognized him for, and goes as far as delivering a few suggestive hip thrusts to compliment his 'swag' adlibs. Bieber's sophomore album Believe is set to hit shelves June 19. Enjoy.
