Michael Jackson was mobbed by fans yesterday as he left a medical centre in Beverly Hills.
The singer wore a surgical mask, hat and scarf over his head as he exited via the back door.
He stopped briefly to sign autographs before hopping into his car, clutching a bag of crisps.
A biographer recently said Michael, 50, had genetic disease A1AD, which deprives the lungs of protein.
But the star's rep, Dr Tohme, rubbished the claim.
