Jeremy Piven is Morphing Into Ari Gold

Move over Paris and Firecrotch, Piven is on fire! "Entourage" star Jeremy Piven and actor Stephen Dorff nearly came to blows after trading insults in the wee hours of yesterday morning at New York HotSpot Bungalow 8. Page Six is reporting that both actors - who had come from Sean Combs' party at Pink Elephant after the Council of Fashion Designers of America Awards - were, according to many spies, "well lubricated" when they showed up at Bungalow at around 1:30 a.m.

Piven, a well-known swordsman who once made out with four different women in 10 minutes in front of a Page Six reporter, had just gotten done telling our spy how he wanted to "score with chicks," when Dorff - who was in "Blade" and "Cecil B. DeMented" - cut the bathroom line in front of him.

According to a source, the altercation was "very high school."

Piven: "Yo, what are you doing? You know you don't need to cut the line!"

Dorff: "I can do what I want!"

Piven: "No, you can't!"

Dorff: "Yes, I can!"

Piven: "You're a has-been!"

Dorff: "At least I am a movie star - you're only on TV! Cable TV!"

The last comment caused Piven to scream expletives, and security guards were called before the two could come to blows. A witness said, "Jeremy, who actually had a table, was shoved into a bathroom by security and left shortly after. And Dorff, who was in the standing-only section, kept hanging around all night telling anyone who would listen, 'I am going to kick Jeremy Piven's ass!' It was hilarious."

Dorff ended up at 5 a.m. at Scores West, telling strippers, "I'm a movie star - you should want to sleep with me," according to one member of his entourage.

Page Six tried to call Piven's rep Siri Garber, but it appears that Siri fired him Monday. "He has morphed into his obnoxious 'Entourage' alter ego, Ari Gold," a source said.

Last week, Piven was "obnoxious" at the "Entourage" premiere at the Arclight Cinemas in L.A. Spies relate that he kicked Garber out of her seat midway through the screening "so some hot chick he had just met could sit down. He was loud and awful to her. Siri has been with him forever and done everything for him - he is a pig."
