Exclusive interview with Katherine Jackson on Piers Morgan

After his sons appeared on Piers Morgan Tonight last week, on Monday May 14th it was mom Katherine Jackson who appeared on the show. Piers Morgan invited Katherine Jackson into the studio for a candid and revealing face to face interview. Joining Piers for an hour long, worldwide exclusive, Katherine addresses her son's legal troubles and prescription medication use, evaluating the role each may have played in the stars 2009 death.

"I think a lot of that was exaggerated, about the different things that he was taking, because I've been to my son's house unannounced and I've been there announced," explains the 82-year-old matriarch. "I have never seen him in that way. I know he was taking painkillers, because he got burnt on the top of his head. Very painful. But all this other stuff they added to it, I don't know if that was the truth or not. But I don't think that have anything to do with the way he died."

Asked by the host about Conrad Murray, Mrs Jackson struggles to find the proper words: "You know what, I can't even describe the way I feel about him. He did a terrible thing," she says of the Michael's former personal doctor. "For a person's life, four years in jail is not enough. I'll never see my son again. But he can get out and he'll enjoy his children."

Watch the clips, and listen to the interview as Katherine Jackson admits she's still mourning her son Michael, saying: "If I wake up through the night, my mind is there."
