All in a day's work!

Justin Bieber dropped by Hillsong church for a service last night, and after he was finished, he decided it would be a good time to decorate his Christmas tree... shirtless!

The "Sorry" crooner posted a video of himself trimming the tree in nothing but khaki pants, and although you don't see Selena Gomez in the clip, it looks like they were at her house, because the decor is very girly.

It's definitely a very merry holiday season for The Biebs, as he's finally won back his one true love. Although the "Come & Get It" songstress' parents are less than thrilled with the reconciliation, he's hoping they'll come around once he proves that he can be a better boyfriend. His fam couldn't be happier, though!

"His parents love Selena. That want him to date someone and think she is very sweet and a good girl. They are happy with how Justin is doing and his focus. They support him going to church often and having his faith being such a big part of his life," a source dished to E! News.

"They think that being back together with Selena is a positive thing. He wants to do things differently and make it right and show everyone how far he has come," the source added.

He's new and improved just in time for the new year!
