He'll wear just about anything to get a rise out of his audience, but has Sacha Baron Cohen's latest controversial costume choice gone too far? The "Borat" star is set to be among the star-studded crowd at the Oscars this Sunday (February 26), but according to Deadline Hollywood, the Academy of Motion Picture Arts & Sciences has pulled Cohen’s tickets due to his wardrobe. On Wednesday night (February 22), reports surfaced that Cohen planned to show up to the red carpet dressed in full character from his upcoming envelope-pushing comedy, "The Dictator." A rep from the film's production company, Paramount, spoke out about the matter, telling Deadline, “Unless they’re assured that nothing entertaining is going to happen on the red carpet, the Academy is not admitting Sacha Baron Cohen to the show.” However, it's still uncertain whether the actor has actually been forbidden from attending, as an Oscar spokesperson has since told The Hollywood Reporter, “We haven’t banned him, we’re just waiting to hear what he’s going to do.” Sacha is part of the Paramount film "Hugo," which is up for eleven Oscars including best picture.
