My how times have changed!

While the rest of the world was out celebrating Halloween last night, Justin Bieber and Hailey Baldwin were getting their prayer on at church in LA. Talk about an old, boring married couple!

Speaking of which, they are indeed hitched, but they're trying to keep things on the down-low for a while longer.

"Justin and Hailey are legally married, but Justin is telling friends he isn't planning on wearing a wedding band for a while. As much as Hailey and Justin are public about their relationship, they are trying not to make a spectacle of it, and that is why they kept their marriage under wraps and got engaged without telling anyone," a source dished to ET.

"The couple kept their marriage a secret from a lot of people. They still plan to have a more formal wedding, but for them, this intimate ceremony was exactly what they wanted," the source added.

Is it bad that we miss the days of wild JB?!
