Michael Jackson's penchant for peeing in public is the real reason behind his 1993 child molestation charges, according to the late star's skin doctor.

Dr. Arnold Klein insists the King of Pop's accuser could identify marks on the singer's genitals because he had seen Jackson urinating.

The pop star was shamed into settling out of court with the young accuser, and the claims against him left many questioning whether Jackson was an appropriate mentor to the children he would surround himself with at his Neverland Ranch home in Santa Barbara, California.

But Dr. Klein insists prosecutors would have failed to bring charges against Jackson if the case had gone to trial because their whole case was based on the fact that the plaintiff could describe the discoloration of the pop star's testicles and penis.

The doctor tells TMZ.com that Michael liked to pee for an audience - and many people could describe the singer's genitals.

The website, which has obtained files from the 1993 molestation investigation, reports, "A deputy from the Santa Barbara Sheriff's Department noted the young accuser was able to describe - in explicit detail - the discolouration on Jackson's genital area... the result of Vitiligo. Dr. Klein insists Jackson did not molest the boy, and says the reason he could describe Jackson's genitals is because Jackson liked to pee in front of other people. Dr. Klein said Jackson thought it was funny. Klein says there were numerous times when Jackson would pee in the doctor's home - around groups of people, including children."
