"The most difficult thing is to sit in this court and listen to all the bad things they're saying about my son. A lot of those things are just not the truth," Jackson, 83, told the court before describing her family's meager start and early musical history.
"I know my son was a very good person," she said. "He loved everybody. He was in the Guinness Book of World Records for the entertainer who gave the most to charity."
Anticipation for her testimony was high as fans have turned out at the courthouse over the past few weeks to show her love and support as the mother and grandmother appeared at the public trial on behalf of her late son.
"Michael was always sensitive and loving," Jackson said as a photo of Michael as a toddler was shown to the court. "Yes, he was born that way. Even in my arms, he couldn't keep still. He was dancing to the music."
Katherine has been a determined motherly presence in the Los Angeles courtroom where attorneys for her family claim the tour promotion company, AEG Live, was negligent when it hired Dr. Conrad Murray to supervise the medical care of Michael.
Katherine also spoke about the kind of father Michael was to his children. He wanted be a father "more than anything else," she said. "He was one of the best fathers. You'd be surprised. It just changed his life."
As images of Michael with his children on his lap are shown in the background to his hit "Speechless," a teary-eyed Katherine said that's one of her favorite songs, while fans in the courtroom mouthed the words.
When Katherine was asked if she misses her son, she said, simply, "Words cannot explain."
The singer died in a overdose of the surgical anesthetic propofol in June 2009. Murray is serving a four-year prison term for manslaughter in the case.
AEG has denied wrongdoing and claims Michael is the one who hired Murray and desperately sought the drugs for sleep that eventually killed him.
Already two of Michael's children have testified in the trial. His oldest son, Prince Jackson, 16, painted his father as loving, devoted and playful in emotional testimony in June, which included a family Christmas video clip.
Videotaped testimony of daughter Paris, 15, who is recovering from a suicide attempt in a residential treatment facility, was also shown to the court.
Witchy wants to know do you expect her to believe that ...Witchy's thoughts on this matter :
If only she could have been this loving when she knew her children were being beaten by her husband and did nothing.
I understand the mother's pain,but think this shouldn't be happening for the children's sake,Michael's gone,the Dr.got sentenced,it was between Michael+his Dr.,enough is enough.
