Post Malone and Justin Bieber have an interesting friendship. It includes collaborations, tours and sometimes doing really violent and painful things to each other.

In the pages of the latest edition of Rolling Stone, Post gives Biebs some tough love by calling out his relationship with the cult-like Hillsong church.

“He’s gotten super-religious recently. Real culty… He’s already given them [Hillsong], like, $10 million. Those are the worst kinds of people. I used to be super-religious. I believed in God. But now I see through it. 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.”

Rolling Stone reached out to Bieber on Post's Hillsong claim, and Bieb's peeps denied he's given eight figures to the church.

But it does seem that Bieber is quite chummy with the church's stylish pastor Carl Lentz. There were rumors that Lentz was the one who got Biebs to cancel his tour this summer and earlier this month Justin and his new old girl Selena Gomez were seen praying at a Hillsong service in LA.
