Why we love ''Entourage'''s Jeremy Piven
WHAT HE'S DOING Piven plays Ari, the superficial and soulless agent of up-and-coming actor Vince Chase (Adrian Grenier).
WHY HE'S HOT RIGHT NOW EW's critic Ken Tucker wrote that Piven plays the part with ''furnace-blast vulgarity.'' (That's meant in a good way.)
BREAKOUT MOMENT Ari embodied all the evil that is Hollywood when he ripped Vince's well-intentioned friend and manager, Eric (Kevin Connolly), to shreds for a questionable business decision, then tried to make nice by saying, ''Let's hug it out, bitch.''
