He’s the consummate Hollywood ladies’ man, and she’s one of the hottest up-and-coming actresses out there. And yesterday (October 29), Adrian Grenier and Isabel Lucas were spotted enjoying each other’s company.

The “Entourage” stud and the “Transformers: Revenge of the Fallen” babe, who have been an item in the past, were out and about in Los Angeles, laughing and smiling all the way.

Although, when Miss Lucas discovered that she was being photographed with Grenier, she quickly hid, raising questions as to the nature of their relationship.

Coming up on New Year’s Eve, Adrian is scheduled to be the star guest at a massive holiday party on Australia’s Gold Coast, which also happens to be Isabel’s homeland.
