Will.i.am: Michael Jackson's Voice Is Still Perfect

Will.i.am has allayed fans fears that Michael Jackson's voice may have suffered during the decade since his last live performance, saying it is still perfect.

Many have suggested that Jackson's vocals may not be up to the task of performing live ahead of his London residency this summer.

However, Will.i.am has revealed that during recording sessions Jackson was nothing short of perfect after three hours of warming up.

He told Starpulse: "He was in my house. It's one thing you hear rumors, but when the guy's in your house, laying on your floor as you're playing beats, he's like, 'Will.i.am, I love this beat.'

"He's laying and his feet are up on the chair, he's kicking his feet. I'm like dude, Michael Jackson's laying on my floor. He's testing his voice and three hours has passed.

"He's just mi mi mi mi mi mi mi mi mi, mi mi mi mi mi mi mi mi mi. He's doing both voice testing just to sing for five minutes. He's testing his voice for three hours to sing for five minutes.

"I don't know. Fergie don't do that sh*t. Usher don't do that sh*t. None of the people that you think still got it do that. I've seen it, in my house. That's because he's a perfectionist and he just likes testing his voice.

"I'm like, 'Dude, can we record now? Because it's three hours, and it's only going take five minutes.' 'No, I just want to warm it up.' Like dude, that's hot. It's warmed up. And he has it. I've seen it. He mi mi mi'd for three hours. Perfect pitch."
