Isabel may or may not have been creepin' on Adrian, but she pissed him off enough to make him hump her and dump her. After Isabel was caught in the truck with Shia LaBeouf during his drunken accident bust, Adrian was reportedly upset, but he kept banging her. Was she apologizing via blowjobs?

Okay, before I post what People magazine's saying, I just have to say this is bullshit. The two were photographed together as recently as last week. Three weeks ago, my ass!

The pair broke up about three weeks ago, right after the accident that left LaBeouf with a crushed hand.

"It wasn't working out," says a source. "Adrian saw her with Shia and that was kind of it �" the crash, their hanging out. He obviously didn't appreciate it."

"He obviously didn't appreciate it." - Hahaha! Adrian's "source" is like, you can't play a player, bitches! Adrian sounds all jealous and shit. That's kinda hot. But only coming from him.
