Investigative journalist Diane Dimond, who has been covering Michael Jackson since 1993, talks to ET about the latest bombshell from the King of Pop's will.

Earlier today, ET reported that Michael Jackson's will states that if his mother, Katherine Jackson, is unable to raise his children, he would like Diana Ross to take over the care of his kids.

"Michael always idolized Diana Ross," Diane tells ET. "There were reports he always wanted to look like her. When Michael and his brothers first moved to Hollywood, Motown sent them out ahead of the rest of the family. Katherine Jackson was beside herself that her son was living with Diana Ross. She's always felt a jealousy with Diana Ross. I can't see how this pleases Katherine Jackson one iota."

Diane also addresses the reports that the drug Diprivan was found in Michael's home.

"Diprivan is also known as milk of amnesia," Diane says. "It puts you to sleep for surgeries. It is not for home use. Individuals are not supposed to have it. It does give you a euphoric feeling after it wears off."
