Could Michael Jackson’s older son have the same rare skin condition that the King of Pop steadfastly maintained he had?

White patches of skin under Prince Michael’s arm were noticeably visible when he wore swim trunks on a recent Hawaiian vacation, prompting speculation that the skin-bleaching disorder vitiligo could be the cause.

Michael Jackson said the condition was to blame for the gradual but steady lightening of his own skin and with his 13-year-old son displaying similar symptoms, skeptics who question the paternity of Jackson’s children may finally be convinced that the singer really was the teen’s biological father.
