If you want to be part of actor-turned-musician (trend alert?) Adrian Grenier's "Entourage," better get in line. Sports Illustrated swimsuit model Melissa Keller, actress Isabel Lucas (who may have two-timed him with Shia LaBeouf), Paris Hilton and his latest conquest Ashley Greene are just a few of the classy ladies who've been linked to the pretty boy. He denies the relationship reports with Hilton, claiming he was merely filming a documentary with her. Nice try. That's what Rick Salomon said, too.
