Praying away the guilt, are we?

Justin Bieber headed to church last night with his buddies, just hours after his hot hookup with model Baskin Champion. JB and the Sports Illustrated stunner had a sleepover after catching the Craig David concert the night before, and now rumors are flying about what this means for his romance with Selena Gomez.

It sounds like The Biebs is simply using the poor girl to get under SG's skin and get her to come crawling back to him.

"Justin knows everything he's doing is going to get out. [Gomez is] off having fun with her friends and so he’s showing that he can still go out and have fun too. And to be honest, I’m sure there’s a part of him that wants to make Selena a bit jealous! This seems like right out of the old Justin’s textbook! He was very manipulative with her emotions the last time and did stuff like this a lot," a source told ET.

"A lot of her friends really don't like him. They think he's bad news for Selena and don't approve of the relationship. They think he’s a bad influence on her and she becomes really dependent on him. She's so generous and loyal and puts 100 percent of herself into everything, including her relationships, which isn't always the healthiest," the source added.

Maybe he isn't a "changed man" after all?
