The boys of "Entourage" are back in action -- and last night, they got their party on to celebrate the show's final season.

Executive producer of the show, Mark Wahlberg, was on hand for the premiere party -- as well as Lenny Kravitz and the show's leading ladies Emmanuelle Chriqui, Perrey Reeves and Debi Mazar.

The new season kicks off June 27.
