All eyes will be on Michael Jackson's two eldest children as they are expected to be the star witnesses in a wrongful death suit filed by the family against the concert promoters who sponsored the singer's ill-fated "This Is It" tour.

The trial, which begins today in Los Angeles, is expected to last three to four months. Prince, 16, and his 14-year-old sister, Paris, are expected to testify about their father's final days leading up to his 2009 overdose death.

The civil suit filed by Katherine Jackson, 82, and the Jackson kids claims Anschutz Entertainment Group (AEG) was aware Michael Jackson was "not psychically well." The suit also alleges that AEG put "its desire for massive profits over the health and safety of Michael Jackson."

The Jackson family claims that the company "committed negligence against Jackson" by requiring him to be treated only by the doctor AEG hired, Dr. Conrad Murray.
