Kelly Osbourne stormed out of an interview backstage at the Brit Awards in London on Wednesday (14FEB07) after slapping guest presenter Matt Willis live on TV. The 22-year-old daughter of rocker Ozzy was due to comment on the ceremony shortly after it finished on British channel ITV2, but the interview was cut short when she began to row with the former Busted singer and hit him just as they went on air. A spokesman for the channel says, "Matt was preparing to interview Kelly when the camera switched to them early. Then they started arguing and Kelly slapped Matt before storming off."
