Adrian Grenier and the other members from Entourage arrives for the 60th Primetime Emmy Awards .

The awards take place on Sunday (September 21) at the NOKIA Theatre in Los Angeles, CA.

Adrien Grenier has denied he was dumped by ex-girlfriend Isabel Lucas so she could be with Transformers : Revenge of the Fallen  co-star Shia LaBeouf.

The Entourage actor denies they were ever even a couple, he said, “I thought it was funny that suddenly there was a big scandal, because since when were we dating? First of all, we don’t give each other those labels - it’s more subtle than that. She and I have a very open communication. We’re friends with common interests. Secondly, love and relationships are complicated. No one could ever get it right in a four-line sentence. I’m not married. We’re young in Hollywood and having fun.”

Entourage returns to HBO on Sunday, September 7.

Adrian Grenier is featured in this weeks Page Six Magazine and the Entourage actor doesn’t want to speak about his relationship with Isabel Lucas.

On Isabel Lucas: She and I have a very open communication. We’re friends with common interests. If you want to know the whole story, you’ve got to be my friend. It’s easy to put those labels on people, but they’re not accurate. We’re young in Hollywood having fun.

On his documentary about the paparazzi: They’re trying to earn a buck in a fun way… so they’re doing what they can to feed that demand and make money. Through my documentary, I’ve realized how insignificant all that is, because I know who I am. Take one part truth and 1,000 parts speculation and heresy, and you’ve got yourself a tabloid story.

On Paris Hilton: I have a lot of respect for Paris. She’s ballsy. She’s learned to play with the paparazzi attention and have fun with it, and she creates little mysteries in the tabloid arena. I have fun with her, but it’s always been platonic. [Our relationship] wasn’t sexual though I understand that sex sells.

Earlier today we posted photographs of Shia LaBeouf out with Isabel Lucas and we asked if you thought they were a couple.

This came only a couple of days after photographs of Adrian Grenier out with a bunch of mystery girls at the beach.

Well now a source has told People that Lucas and Grenier split up right after she was in a car accident with LaBeouf.

The source said “it wasn’t working out, Adrian saw her with Shia and that was kind of it – the crash, their hanging out. He obviously didn’t appreciate it.”

We thought Adrian Grenier was dating Isabel Lucas but on Sunday (August 10) the Entourage actor was spotted with a bunch of girls at a beach in Malibu, CA.

After playing around in the water and enjoying a bit of sunbathing, the group all headed off to dinner at Nobu restaurant.

This is the girl who was in Shia LaBeouf’s passenger seat when he crashed his car on Sunday morning. Isabel Lucas is an Australian actress who came to fame on Home And Away and is going to be in the upcoming Transformers: Revenge of the Fallen, the sequel to original Transformers.

Lucas wasn’t seriously hurt when LaBeouf flipped his Ford F150 after making an illegal left turn and got broadsided. She was treated for minor head injuries while Shia had to have surgery on his left hand, he is taking a month off from filming Transformers 2 to recover his hand.

NY DailyNews report that Lucas has been dating Entourage star Adrian Grenier since February and the actor is said to be unhappy that she was partying with LaBeouf all night.

While UsWeekly report that LaBeouf and Lucas were out at Troubadour club in Los Angeles, CA and Shia was “dancing around and acting really crazy, He kept doing shots of whiskey.” His mother then told the magazine that “He is doing really well… Thank you so much for asking.”

Leighton Meester and Nicole Fiscella spent the day together on Thursday (July 10), the pair of them were spotted hanging out together in Greenwich Village in New York City.

Along with being in Gossip Girl, Leighton can soon be seen in the fifth season of Entourage, she will reprise her role of Justine Chapin, a love interest for Vince (Adrian Grenier).
