London, Jan 16 : One-time Ling of Pop Michael Jackson has sparked new fears for his health after he left a hospital sporting a bizarre surgical mask, scarf and a hat.

The `Thriller' hitmaker added fuel to the claims about his deteriorating health after he was spotted living the L. A. clinic.

Although, Michael was wearing a mask in a bid to avoid fans and media frenzy, his ever-loving fans recognized him and hurdled up to him for autographs.

After signing autographs, the singer casually munched on a packet of crisps, before boarding his chauffeur driven jeep, reports the Daily Star.

Recently, Michael's biographer Ian Halperin had alleged the star is half-blind and needs a lung transplant for a rare protein disorder.

However, Michael insisted he is fighting fit and ready for a global tour. (ANI)
