After the CFDA Awards was Diddy's after party, where Jeremy Piven shoved his mug into just about every shot the camera took. After the after party (but before the hotel lobby) Piven took his formerly lovable antics to Bungalow 8 to throw down with some ruffians, well, Stephen Dorff at least. Page Six recounts their awkwardly-too-old-to-be-doing-this-but-at-least-it's-not-Axl-and-Tommy-again dude scuffle:

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 our 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!"

Unbeknownst to Dorff, Jeremy Piven was rubber and he himself was glue, thereby enacting the dreaded bounce-stick volley that ultimately crowned Piven the winner of the argument.
