Entourage star Adrian Grenier has reportedly called it quits with girlfriend Isabel Lucas in wake of rumors that the actress is involved with Transformers co-star Shia LaBeouf.Lucas was LaBeouf's passenger at the time of his car crash late July, and sources claim she split from Grenier days later.
“The relationship wasn’t working out for either of them," a source 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.”
