The cast of the Twilight movies appeared on the MTV Video Music Awards show Thursday night -- all, that is, except Kristen Stewart, who has been publicly chastised by fans for having an affair with the director of Snow White and the Huntsman -- an affair that ended her relationship with her co-star and boyfriend Robert Pattinson. But host Kevin Hart was unwilling to stay silent about what he called "the elephant in the room." He told the audience, "Everybody's mad at Kristen Stewart for making a mistake. ... She allegedly messed around with the director of Snow White and the Huntsman. ... If she did, so what? It's over. Move on." Introducing a clip from Breaking Dawn Part 2 , Pattinson told the crowd, "It has been an amazing Journey and we would like to thank all the fans of the series for their incredible enthusiasm from the beginning until now, the final chapter." The clip then began with Pattinson's character telling Stewart's, "I have a bad habit of underestimating you."
