The latest bulletin about Michael Jackson from the American Music Awards front is in. (The show, to be aired by ABC, takes place tonight at L.A.’s Shrine Auditorium.) And that is, the Gloved One, 43, is due to dust off his 1988 “Man in the Mirror” and deliver it during the ceremony, reports Reuters, despite the fact that the number could hurt his chances of performing on the Grammys (to be broadcast live Feb. 27 on CBS). Then again, Jackson will not be performing the song live, but, rather, on a videotape that, his publicist says, was recorded “very recently.” AMA producer Dick Clark is suing president of the National Academy of Recording Arts & Sciences Michael Greene, who oversees the Grammys, for $10 million. Clark claims that the Grammys are allegedly blackballing artists who perform on his show. “We have 980 nominees and only 14 performance slots. So who in their right mind would want to regurgitate something that was on just a few weeks earlier?” Greene told Reuters. Jackson is expected to pick up his AMA “Artist of the Century” award in person tonight — after he initially withdrew from the show in order not to spoil his chances of appearing on the Grammys. (He garnered only one nomination this year.) It was Jackson’s initial withdrawal from the AMA that reputedly inspired Clark to sue.
