It's pretty obvious what went down last night!

Justin Bieber was up bright and early at 7:30am to drive Sports Illustrated model Baskin Champion back to her house after they spent the night together, and it doesn't take a rocket scientist to figure out that they clearly hooked up! The two were spotted leaving the Craig David show together last night in LA, and it seems like they moved the party from the club to the bedroom.

Our photographer asked JB if the blonde beauty was his new girlfriend, and he just wagged his finger from inside his blue Lambo. We bet he's freaking out, because he probably didn't think we'd be on the job this early in the morning catching him in the act!

Our photographer tells X17:
    "Justin seemed shocked and nervous when he saw the cameras. He was doing his best to hide his face, and he just had this look of guilt like he knew he was going to hear about this."

So just how did these two meet? Well Baskin's the model sister of Patrick Schwarzenegger's girlfriend Abby Champion. And Biebs and Patrick were just hanging out the other night at the premiere of Schwarzenegger's new film Midnight Sun. Hmmm ... a little double-dating opportunity!

This surely isn't going to help the status of his rocky romance with Selena Gomez!
