According to reports, late pop legend Michael Jackson slept with his eyes open.

Newsoftheworld. co. uk has reported that the dead star's ex-wives and lovers are to be called to testify to confirm the latest astonishing fact about his private life, as their evidence will be used by defense lawyers representing Conrad Murray as he fights a homicide charge.

Murray aims to prove how difficult it was to tell whether Jackson was asleep or awake.

Debbie Rowe, mother of the King of Pop's eldest kids Prince and Paris, Lisa-Marie Presley and nanny, Grace Rwaramba, who he called his "wife", will be quizzed at Murray's trial this year.

It was also reported that the cardiologist's defense team have evidence the seasoned drug user often appeared awake when asleep.

They say he would have his eyes open and his pupils would be dilated when he was on Propofol.

A defense source has said, "Conrad Murray's future is at stake here and we will do all we can to prove that he did not deliver a fatal overdose to Jackson. We are going to call the significant others in Jackson's life to talk about his long-term drug use and behavior."

The source further added, "We've found he would appear dopey and sleep with his eyes open when he had taken meds. We want the women closest to him to verify this. We'll also ask his doctors about how he slept after being knocked out. This could be a key part in the defense... This wasn't a case of a doctor giving a fatal dose to a clean patient. Jackson had a long history of extensive drug use." (With Inputs from Agencies)
