Funny how when she was with Younes she didn't feel the pressing need to attend services...

Kourtney Kardashian went to church last night for the first time in months, and it just happened to be the same night Justin Bieber and Hailey Baldwin were there. Coincidence? We think not! It's gotta be awkward for JB's lady love to have his former fling running in the same circles.

"Things between Justin and Kourtney were more serious than most people realized. Their physical compatibility was off the charts, and they even started to bond about religion. Justin was hugely attracted to Kourtney, and she was really smitten by him. They had a lot of fun together," a source dished to Radar.

"Hailey is very protective of her relationship and she has every reason to feel threatened. She's saying that Kourtney better stay away from Justin, and she won't hesitate to ban him from speaking to her altogether," the source added.

Kourt is totally the type to flirt with The Biebs right in front of his fiancee!
