Sean Penn – punch drunk love?

E! reports two-time Oscar winner Sean Penn was kicked out of one of Hollywood's most prestigious post-Oscar parties, the Governor’s Ball, on Sunday night for fighting with one of The Hurt Locker’s producers, Greg Shapiro. Greg is said to be dating Sean's still-not-actually-ex-wife, Robin Wright. Naturally, denials abound, with Sean's rep insisting he wasn't there and chose to attend the Sunset Tower Hotel after-party instead. Backstage reports and his onstage speech at the Oscars indicated that all was not well in Penn-land on Oscar night, though.
