Katherine Jackson Testifies -- It Hurts to Hear Michael Jackson Called 'Freak'

Breaking News

Katherine Jackson testified in her wrongful death lawsuit against AEG Live ... it's devastating to hear witnesses and lawyers refer to her dead son as "lazy" and a "freak."

She said, "It's hard to sit here in court and listen to all these things ... My son was sick and nobody was trying to help him."

When she met Dr. Conrad Murray -- the man who killed MJ with a fatal dose of Propofol -- she said she immediately thought the doc WASN'T the right person to care for her son.

She said, "My son needed another doctor."

Katherine is trying to prove AEG was negligent in hiring and supervising Dr. Murray, and is therefore responsible for the singer's death.
