Prince Jackson's day in court arrives Jackson children in the spotlight Jurors will hear revelations about Michael Jackson's tearful conversations with his son His father confided in Prince about whom he distrusted It's possible jurors will see video of Paris Jackson's deposition as Prince is cross examined The wrongful death trial of AEG Live is in its ninth week in a Los Angeles courtroom Los Angeles (CNN) -- Prince Jackson, who wore a mask in public as a child, will appear in court Wednesday to testify about his father's life and death. Michael Jackson's oldest son was 12 when the pop icon died. But his father confided in him about whom he trusted and didn't trust, and what he feared as he prepared for his comeback concerts. Four years and a day after his father died, the 16-year-old's testimony promises to be the most dramatic in the wrongful death trial against Jackson's last concert promoter. Jurors will hear revelations about Jackson's tearful conversations with his son, which included predictions of his death, and details of their private lives that would thrill any tabloid editor. Prince, Paris and Blanket Jackson, and grandmother, Katherine Jackson, are plaintiffs in the lawsuit that contends AEG Live is liable in Jackson's death because the company hired, retained or supervised the doctor convicted of involuntary manslaughter. Dr. Conrad Murray told investigators he gave Jackson nightly infusions of the surgical anesthetic propofol to treat his insomnia. The coroner ruled the singer died of an overdose of the drug. AEG Live executives allegedly created a medical conflict of interest that pressured Dr. Murray to pursue the dangerous treatments so Jackson would be rested for rehearsals, while ignoring warning signs that his health was failing, Jackson lawyers argue. AEG Live lawyers contend that it was Jackson who chose and controlled the doctor and that company executives had no way of knowing what treatments Murray was delivering. Daddy's little man Jackson lead trial lawyer Brian Panish will begin the direct examination of Prince on Wednesday morning and AEG Live lead lawyer Marvin Putnam is expected to handle the cross examination of the teen later in the day. It is possible that jurors will also hear from Paris Jackson on Wednesday since Putnam could play video clips from her deposition in an effort to highlight any contradictions between brother and sister. Paris, who was 11 when her father died, is not available to testify live in court since she is hospitalized for psychiatric treatment following a suicide attempt earlier this month. AEG Live attempted to compel the youngest child -- 11-year-old Blanket -- to testify but the judge rejected their request after a psychologist said it would be harmful to the boy. Jackson confided in his oldest son about his business dealings at an early age. "Prince has always been, even at 12, the little man -- daddy's little man," Jackson chef Kai Chase testified. Prince recently began pursuing an entertainment career, working several days as a "special correspondent" for "Entertainment Tonight" and acting in an episode of the television show "90210." MJ's two-month decline Prince will be asked to describe how his father's health changed from April 2009, just before Dr. Murray began his nightly visits to their rented Los Angeles mansion, until his death on June 25, 2009. E-mail introduced as evidence and previous witnesses have told of a physical and mental deterioration over Jackson's last two months. Show director Kenny Ortega and production manager John "Bugzee" Hougdahl warned AEG executives of Jackson's deterioration during a series of e-mails in Jackson's last two weeks, including indications he was unable to do some of his trademark dances or remember lyrics to songs he had sung for decades. Associate show producer Alif Sankey testified that she "had a very strong feeling that Michael was dying" after a rehearsal 11 days before his death. A Harvard sleep expert testified last week that Jackson's downward slide toward death could be explained by the insidious effects of chronic infusions of propofol. The nightly treatments likely interrupted Jackson's sleep cycle, robbing him of REM -- rapid eye movement -- sleep, which is vital to keeping the brain and body alive. "The symptoms that Mr. Jackson was exhibiting were consistent with what someone might expect to see of someone suffering from total sleep deprivation over a chronic period," said Dr. Charles Czeisler, a Harvard Medical School sleep expert. The trial is in its ninth week and is expected to last until August.
