Michael Jackson's skin doctor Arnold Klein was completely rebuilding the star's ravaged face in the run-up to his This Is It comeback shows.

Klein desperately tried to make the King of Pop appear "more normal" for his 50-date run at London's O2 Arena after years of cosmetic surgery left the singer's face severely scarred and acne-ridden.

However, the dermatologist insists rumors the star's nose was so bad it had fallen off his face are untrue.

Klein tells TV host Larry King, "He came to me because, basically, I was sort of rebuilding his face, because he had severe acne and scarring. He had scarring from having a lot of cosmetic surgery. And my expertise is like it is with every one of my patients. My patients are my treasures. And I was rebuilding his face so he looked much more normal. And contrary to what people said, he could not take off his nose. His nose was attached. But it looked too small. And I just was trying to get him ready to do the concert, because in the way he looked in his face, he wanted it to be absolutely as perfect as it could be."

Klein also confirms Jackson was paranoid about his nose after years of taunts from his family: "I know that people made fun - or family members - of the size of his nose. He was very sensitive to that. And so he (started) doing cosmetic surgery."
