Shirtless Justin Bieber Decorates His Christmas Tree: Watch!

‘Tis the season!

A very Bieber Christmas! Justin Bieber is ensuring his Beliebers’ holiday season is both merry and sexy.

The 23-year-old “Sorry” singer took to Instagram in the early hours of Thursday morning to share a sped up video of himself shirtless and decorating his Christmas tree.

Set to the tune of “Jingle Bell Rock,” the Biebs zooms around the tree adding red, gold, and white ornaments to the branches.

Bieber hasn’t clarified his holiday plans yet, but they will like involve his new on-again girlfriend, Selena Gomez. The pair officially reunited in October after years of on-again, off-again romance.

But a source recently told ET that Gomez has influenced Bieber for the better.

"Selena is 100 percent the reason Justin turned his life around," the source said. "She's the one that got him involved with church and that opened up a whole new group of friends to him too… Justin wants to be a better man because he doesn't want to screw things up with Selena.”
