London, July 12 - Pop legend 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.

Dailyexpress.co.uk reports, 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.

The dermatologist, however, insists rumours that the star's nose was so bad it had fallen off his face are untrue.

'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.
