The phrase "party hard" and Vinnie Chase have gone hand-in-hand over the course of seven seasons of "Entourage," but it looks like Vinnie has hit his lowest point in recent episodes, thanks to tequila and the irrepressible charms of Ms. Sasha Gray.

By the end of "Hair," a drunk and naked Vince lies face down next to his pool while Eric and Ari hover over him, ready to tackle the biggest career move of the young actor's life. Can Vince even pull himself together enough to land the "Airwalker" deal? Next week will uncover this mystery.

Turtle has a problem sealing a deal with Alex due to some physical discrepancies. The two get over their baggage and make the first real move towards building a true foundation as buddies.

Ari is having some trouble with women as well - Lizzie Grant and Amanda Daniels to be exact, as both Hollywood power players are out to sink the super agent. Lizzie leaks recordings of Ari's rants to "Deadline Hollywood," leaving Gold at a loss for how to repair his already controversial reputation.

The series is nearly at its end, but HBO has confirmed that next summer's six-episode season "will definitely be the final season of the series," possibly leading the way towards a motion picture adaptation, according to The Hollywood Reporter. So get in on the "Entourage" TV gravy train while you can!
