The Biebs was in the hizzy in Los Angeles this evening.

That’s right. Justin Bieber performed ‘The Christmas Song (Chestnuts Roasting on an Open Fire)’ on tonight’s season finale of ‘X Factor.’ The Biebs was not only surrounded by falling faux snow but by the R&B legend known as Stevie Wonder. Generations and genres collided with this duet and it was one of the most mature and vocally proficient performances The Biebs has delivered all year. He is coming into his own as an artist beyond the “teen idol” tag.

Wonder played the piano and harmonica while seated, as The Biebs sang and danced in his black, Drake-like varsity jacket with metallic green sleeves, black trousers and fingerless gloves.

But The Biebs didn’t stop with one song. He also turned up the tempo to perform his peppy, urban-lite version of ‘Santa Claus is Coming to Town.’ He recruited dancers to groove with him and there was even a breakdancer in the mix.

Both of the songs that The Biebs performed appeared on his ‘Under the Mistletoe’ holiday album.

The Biebs even called Drew, a self-professed and mightily proud Belieber, on stage towards the end of his perf. He gave her a big hug and let her sing the final “Santa Claus is coming to town” line in her signature, ethereal Drew style, all the while holding hands with her. She had an ear-to-ear grin and could barely contain herself. She was blushing like crazy.

That Biebs — such a charmer. He just made Drew’s life! He said, “She is a very special girl and she will go far.” Poor Drew looked like her knees were buckling. Wonder, who also appeared on ‘American Idol’ last season, gave props to The Biebs for performing at his benefit show and said The Biebs reminds him of himself when he was young. That’s serious high praise.

All in all, The Biebs brought the holiday cheer and all-around Bieber awesomeness to the stage tonight.
