We bet he's glad to have her back!

Selena Gomez is back from London, and the first thing she did was meet up with Justin Bieber and head to church. These two are so religious these days!

JB enjoyed a casual boxing session before services with Kylie Jenner's BFF Harry Hudson, and he wasn't half bad. Another person he might want to box? Rapper Post Malone! The guys used to be pals, but we doubt The Biebs is cool with the comments he recently made.

Malone called the "Sorry" crooner "super religious" and "real culty" in a Rolling Stone profile, and claimed that he had donated a whopping $10 million to Hillsong.

"It's nice to support something you believe in, I guess. But people are spending so much money, and God doesn't care that your church has a f*cking gold roof," he said.

Not so, says Bieber's preacher.

"I do not know Post Malone, and I have no idea why he would say reckless things about our church, which he has never visited. Justin has not given our church $10 million, and we do not have gold ceilings. We do not even own a church building. So that gives you a little insight about how serious you can take his observations about anything to do with us," he refuted.

Whatever Bieber has been doing lately, it's working. His life is on the up and up!
