Normally this is their favorite activity to do together.

Justin Bieber dropped by church last night to catch a service, and this was one of the only times we've seen him without Hailey Baldwin since they got engaged. Not that there's any trouble in paradise, though. It's actually quite the opposite.

The Biebs has reportedly "never been so happy" since reuniting with the model.

"Justin is in a really good place, and has been telling friends he's never felt more sure about a woman in his life. Justin is head over heels in love with Hailey," a source dished to ET.

"Justin and Hailey get along great, are on the same page about their faith and what they both want out of their future together. It took some time for Justin and Hailey to get back together, but the couple knows it was worth the wait," the source added.

This has all gotta sting for Selena Gomez!
