Adrian Grenier & Isabel Lucas Put Brakes On Relationship

“Entourage” star Adrian Grenier and girlfriend Isabel Lucas have called it quits, People reported.

Adrian reportedly put the brakes on the relationship three weeks ago, just after Isabel was involved in a car accident with “Transformers: Revenge of the Fallen” co-star Shia LaBeouf.

“It wasn’t working out,” a source told People. “Adrian saw her with Shia and that was kind of it — the crash, their hanging out. He obviously didn’t appreciate it.”

The couple had reportedly dated for several months.

Meanwhile, the co-stars were spotted hanging out in Los Angeles on Monday, where Shia, who injured his left hand in the accident, had trouble opening a bottled drink.

As previously reported on AccessHollywood.com, Isabel was Shia’s passenger in a collision with another vehicle in Hollywood on July 27. The crash saw his green Ford truck flip over, crushing his hand.

Isabel, who was taken to the hospital with Shia and treated for minor bumps and bruises following the accident, told Access Hollywood recently that her co-star is getting better following his hand surgery.
