Sharon Osbourne will testify in the Michael Jackson wrongful death trial as she said the concert promoters, AEG Live: " knew he was not well and they didn't care."

The 60-year-old star has been called up as a witness and said she has information which will help the Thriller singer's family's case against AEG Live.

The promoter has been accused of ignoring health concerns over Michael and hiring physician Dr. Conrad Murray - who was convicted of the involuntary manslaughter of the star following his passing in 2009 - and now Osbourne has revealed on The Talk that she has evidence which could help.

Osbourne said: "Whether he performed or not, they'd still make money. I had conversations with people who said exactly that. I will tell people who said it."

The Jackson estate are seeking over $40 billion in damages from AEG Live.
