CNN just aired leaked video from Michael Jackson's last-ever rehearsal for his "This Is It" tour. The footage, shot at the Staples Center on June 24, two days before his death, shows a skinny-looking MJ doing "They Don't Care About Us," which was not one of his better-loved hits (it was that "Jew me, sue me" song that caused an uproar in 1996, back when song lyrics could still cause uproars). But, hey, maybe "Beat It" will leak soon too.
