Michael Jackson's son will testify at his wrongful death lawsuit trial.

Prince Jackson will take the stand in his grandmother Katherine Jackson's civil case against AEG Live - which accuses the company of being responsible for negligently hiring Dr. Conrad Murray to care for the late King of Pop - and is expected to give evidence on conversations he had with his father about the concert promoter.

"Prince absolutely plans on testifying. Prince very much wants to take the stand and plans to tell jurors about specific conversations he had with his father about AEG. Prince will also testify about the fateful day his father died, as he was an eyewitness to the efforts that were made to save his life," a source said.

In the lawsuit, Katherine, 82, contends that AEG Live - which was behind the late singer's This Is It comeback concerts at The O2 arena in London - were responsible for Dr. Murray, who was found guilty of involuntary manslaughter following Michael's death, and failed to properly vet the physician before hiring him. The "Thriller" hitmaker died in June 2009 after being administered a lethal dose of Propofol by Murray.

The 16-year-old's siblings, Paris, 15, and Blanket, 11, aren't expected to testify, however. The trial is set to begin on April 2.
