Michael Jackson's childhood friend and television host Kathy Hilton has said that the audio recording played on the opening day of the trial of Dr. Conrad Murray, charged with involuntary manslaughter, was suspicious.

I thought it was very suspicious and I thought it was very strange and not normal, Hilton said on CNN's Piers Morgan Tonight.

Hilton said she was stunned as the trial proceedings unfolded on the television which showed a lifeless body of the star on a gurney along with Jackson's voice, recorded just weeks before his death. Wouldn't he (Murray) have called somebody right away, a manager or a family member and say, 'You need to get over here and see this'?

As prosecutors played an incredibly sad tape of Michael Jackson's voice Tuesday, spectators in the Los Angeles courtroom looked pained.

The King of Pop said: We have to be phenomenal. When people leave this show, when people leave my show, I want them to say, 'I've never seen nothing like this in my life. Go. Go. I've never seen nothing like this. Go. It's amazing. He's the greatest entertainer in the world.'

Hilton said she was apprehensive about appearing on a television show discussing the ongoing trial and sought Katherine Jackson's permission for the same.

She was agitated that the distressing evidence was shown while Jackson's family sat in the courtroom witnessing the proceedings. When I saw this today, this was criminal. To have his parents and his brothers and sister and children to see something like this..., Hilton said.
