We're not sure we're buying this!

Justin Bieber and Hailey Baldwin are attached at the hip these days, but when it's time to turn in for the night, they go their separate ways! Yep, that's right... the religious couple is allegedly waiting to have sex until after they're married.

"Hailey is a devout Christian and a good girl. [Bieber's mom and Hailey's parents] are born again and they have known each other through church circles since Justin was 10 and Hailey was 6. She was home schooled until she was in her mid-teens and now she is helping Justin to get on the right path,” a source dished to Radar.

"He’s going to church with her. He still has his demons, but there’s hope," the source added, noting that the pair are trying to keep their relationship "pure." Translation - no nookie for The Biebs!

The lovebirds are currently vacationing in Miami, but are already hard at work on planning their big day. This recent info makes us think he's going to want to tie the knot sooner rather than later!

"As of now, they want a small ceremony with their families. They are not planning a huge, celebrity wedding. They are getting married for love and don’t want a flashy wedding," a source told People.

"This is not a joke to him. He proposed because he truly feels Hailey is the love of his life. He had a rough time last year, but he worked very hard to change and find more meaning in his life. Hailey couldn’t make him happier," the insider explained.

JB sounds like a changed man!
