Michael Jackson's eldest son has testified that his father was excited about going back on tour before his death but wasn't happy about the terms of the ill-fated shows.
Prince Jackson told jurors his father wanted more time to rehearse and had several tense phone conversations with promoters of his "This Is It" shows that sometimes ended with his father in tears.
The 16-year-old said his father remarked after one of the conversations, "'They're going to kill me,'" Prince testified. He did not elaborate.
The lawsuit claims AEG negligently hired the doctor who was later convicted of involuntary manslaughter for giving Jackson an overdose of the anaesthetic propofol.
AEG denies it hired the physician or bears any responsibility for the entertainer's death.
The testimony by Prince Jackson began with the teenager showing jurors roughly 15 minutes of private family photos and home videos.
He described growing up on Neverland Ranch and showed the panel videos of the property's petting zoos and other amenities. After his father's acquittal of child molestation charges, Prince described living in the Middle East, Ireland and Las Vegas.
He told the jury that his father was always working, but his children had no idea he was a global superstar.
"We always listened to his music, but we never knew how famous he was," Prince said.
He said he and his sister Paris watched a video of one of their father's performances and got a sense of his fame when overwhelmed fans were carried from his shows on stretchers.
Prince is the first Jackson family member to testify during the trial, now in its ninth week. Attorneys have said TJ Jackson, who serves a co-guardian to Prince and his siblings, and Taj Jackson, are also expected to take the witness stand. They are the sons of Tito Jackson.
Prince Jackson, his sister Paris and brother Blanket are plaintiffs in the case against AEG, which their grandmother and primary caretaker filed in August 2010.
