Michael Jackson is making it clear he won't help sales of sister Latoya's book by joining her in a public name-calling fray.

Says Lee Solters, spokesman for the superstar, "Michael Jackson has no intention of becoming an unwilling participant in Latoya's publicity campaign for her book. She, unfortunately, is making every attempt to draw Jackson into a media melee with her. This is the last statement or comment that will be made about Latoya and her book."
