A four-minute tape in which Michael Jackson confesses he didn't have a childhood has been played at the trial of his personal physician, Doctor Conrad Murray, the man accused of killing him.

Murray told the court he had taped the call on his iPhone soon after starting work as Jackson's doctor,

The four-minute recording was played in full yesterday at the seventh day of

Murray's trial in LA.

On the recording, the drug-addled 50-year-old star — who would die little more than a month later — slurred his way through a speech about his love for children, saying: "I didn't have a childhood. I feel their

pain. I feel their hurt.

"Heal The World, We Are The World, Will You Be There, The Lost Children. These

songs I've written because I hurt."

The Beat It singer also rambled about his This Is It comeback shows at London's O2,

saying: "When people leave I want them to say, 'I've never heard anything

like it in my life. Go. Go.'

"I'm taking that money, a million children, children's hospital, the

biggest in the world.

"Going to have a movie theatre, game room. Children are depressed. I want

to give them that."

Jackson's siblings Randy, Jermaine and Rebbie sat devastated as the

tape was played. It was recovered from Murray's iPhone by computer expert

Stephen Marx, who gave evidence.

Prosecutors allege Murray, who denies involuntary manslaughter, killed the King of Pop

with a huge dose of the anaesthetic propofol, a substance Jackson allegedly used as a sleep inducer and referred to it as his 'milk'.

Meanwhile, a top US legal expert said yesterday Murray's case had been damaged

by testimony from his sexy former girlfriend, wannabe actress Nicole


Sunny Hostin said: "The jury thought she was auditioning for her own reality

show. They hated her."
