MJ's son suffering from same skin disease as 'King of Pop'

The 13-year-old revealed white patches under his arm while on a recent holiday to Hawaii with his siblings Paris, 12 and Prince Michael II, eight, Daily Mail Online reported. While there is the possibility it was the result of sun exposure but it appeared more dramatic than peeling skin, the report said. Vitiligo is a hereditary skin condition which discolours the face and body.

Jackson, who died last year at the age of 50 due to drug overdose, blamed the disease for the gradual lightening of his own skin over the years. His claim was always met with some skepticism from critics, who accused him of intentionally bleaching his skin. Now that Prince Michael is showing signs of similar symptoms, some are convinced it is evidence Jackson really was the teen's biological parent.

For years the paternity of Jackon's children has been under question because of the difference in skin tone. "It proves once and for all that Michael is the father," a family source said. Prince Michael and his sister Paris were born to Debbie Rowe, Michael's wife from 1996 to 1999. Prince Michael II, also known as Blanket, was born to an unknown surrogate after the divorce.
