Actor Sean Penn was reportedly banned from the annual governor's ball shortly after the Oscar ceremony at the Kodak Theater had ended.

E! Online claims that the star apparently had some sort of basckstage confrontation with Greg Shapiro, one of the Oscar-winning producers of 'The Hurt Locker', who is said to be dating Penn's former partner, Robin Wright.

"Minutes after Penn and Shaprio came face-to-face, Academy officials said he was banned from the Ball," sources told E! Online.

Penn's rep insists there was no confronation and that the actor chose not to stop by the Ball. A rep for the Academy would only say, "Sean Penn chose not to attend the ball."

Penn eventually made his way to the Sunset Tower Hotel afterparty. "Fine," he told E! News' Ashlan Gorse when she asked him how his night was.
