Michael Jackson

Jurors hearing a lawsuit involving Michael Jackson's death have heard from a doctor who treated the singer in the early 1990s and believed he had a problem with prescription pain medications.

Dr. Stuart Finkelstein testified today about giving Jackson two doses of painkillers while the singer was on 1993's "Dangerous" tour, which ended prematurely when the superstar entered rehab.

Finkelstein's testimony was shown to jurors after being videotaped earlier this year.

Finkelstein is now an addiction medicine specialist. He testified that he relayed his concerns that Jackson was dependent on painkillers to Paul Gongaware, a promoter who is now a top executive for AEG Live LLC.

Jackson's mother is suing AEG Live claiming it negligently hired Conrad Murray, a cardiologist later convicted of giving her son an anesthetic overdose in 2009.

AEG denies wrongdoing.
