Michael Jackson’s Former Manager Breaks His Silence

Tonight, ET has never-before-seen video of Michael Jackson under oath, a side of the late King of Pop rarely seen -- and his former manager Dieter Weisner breaks his silence about it!

"He was on one side a big beautiful artist," Weisner tells ET's Mark Steines, "and he was such a lonely man -- that was the problem."

Being questioned in a multi-million-dollar lawsuit for breach of contract by a former business associate, Michael appears at times jittery and nervous, sometimes laughing, claiming at one point that he did not testify in a previous case because he was suffering from a spider bite.
