Jazz legend Herbie Hancock was dumbstruck by Christina Aguilera's incredible vocal prowess after recording a track with her.

The Beautiful pop beauty impressed Hancock so much, he hails her work as "perfect" from the very first take.

He enthuses, "I knew she could sing. I knew she could really sing. But I didn't know she could sing like that. She knocked me out. She did her first take and I said, 'Well, you nailed it.'

"And she said, 'Oh no, no, no, that was just a scratch vocal.' Her intonation was so perfect, I mean, not a flaw in it at all."
