A source has told Usmagazine.com that “Entourage” star Adrian Grenier (who plays Vincent Chase) and actress Isabel Lucas have gone their separate ways.

Isabel Lucas was in the car with actor Shia LaBeouf when they were involved in a car accident last month, after which LaBeouf was arrested for DUI and had to have surgery to his hand.

“All that stuff that happened with Shia definitely didn’t help things,” the source tells Usmagazine.com. “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.”
