Adrian Grenier has dumped his girlfriend Isabel Lucas over this whole ‘Shia LaBeouf DUI/truck flipping/hand surgery thing.’ Apparently the Entourage star does not take too kindly to be cheating on with Transformer boy.

“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.”

You can’t have your cake and eat it too Isabel. Although you can’t blame her for stepping on Grizzly Adams. Beards are cool and all…but dudes with afro’s should really resist the urge.
