It's Over for Grenier and Lucas

Actors Adrian Grenier and Isabel Lucas have called it quits. The relationship ended about the same time it became very public. Lucas had been dating the 32-year-old Entourage star for several months, but the relationship wasn't spotlighted until her car accident with Shia LaBeouf. Lucas was a passenger in her Transformers 2 costar's car when he was arrested for DUI on July 27. A source for US Weekly said, "All that stuff that happened with Shia definitely didn't help things. "When Adrian saw Isabel with Shia, he knew it was time to move on and made the decision to end things. He's not upset and thinks Isabel is a really sweet girl but they're done." Lucas's rep told People that the 22-year-old actress is single.
