The stars of "Entourage" hit the town to premiere the fifth season of their hit HBO series -- airing Sept. 7 -- and ET was there to get the show scoop from Adrian Grenier (Vince), Jeremy Piven (Ari), Kevin Connolly (Eric) and Kevin Dillon (Drama).

"To me it's the best season yet," enthused Emmy and Golden Globe winner Jeremy. "It's about real things and it's truthful and I think season five is the best one."

"I think it's going to be a new experience for the audience," added Adrian. "You're going to see things you haven't seen before."
