Justin Bieber's ITV Special aired and the Biebs demonstrated why he is an unstoppable talent. He was able to sing, dance and change tempos, moods and genres seamlessly. Holiday tunes? Check. Acoustic renditions of R&B hits? Check. High octane renditions of his own smash songs? Check. The Biebs did it all and we have video to prove it.

The Biebs performed an intimate, acoustic and flawless version of 'You Got It Bad' by his mentor Usher. The Biebs sort of reminded us of Drake here. It was his quiet take on a song -- his voice is so unique, like Drake is so inimitable. The Biebs is no flash in the pan who will be forgotten when his fans start dating. We also are liking that Bieber has abandoned his signature bangs. He also sang a rendition of Ne-Yo's 'Because of You.'

Bieber also got down with British rapper Tinie Tempah, who rapped the parts of 'Little Drummer Boy' that Busta Rhymes laid down on the studio/album version. Tinie and the Biebs played off one another well. We liked Tinie's red skull cap and scarf -- it certainly heightened the "wintry" nature of the perf. Tinie closed out the song with the Biebs, as they had people waving their hands in the air like they just don't care. It didn't feel quite so Chrismtas'y at that point.

The teen sensation didn't skip out on his own massive hits, either. He performed 'Baby,' and we went deaf for a hot second from the screams of the crowd. Bieber danced his a--- off and even played drums at the end. Remember, we all saw Biebs-as-skinsman in his 'Never Say Never' film. The Biebs really can smash the skins and man the kit.
