`Dr Frankenstein` Michael Jackson`s kids may not be biologically his own

London: Michael Jackson was so determined to have a "perfect family" that he acted like Dr Frankenstein and picked sperm from close friends who he believed were intelligent, good looking and caring.

Brit actor Mark Lester, 54, has claimed to have fathered Jackson`s three kids and a former aide said that the former child star is one of six men who could be the dad of his kids, the Daily Star reported.

Others who could have fathered his kids were said to be a Hollywood A-list star, another former child star, a doctor, a close family friend and an employee at the Neverland ranch.

But only Jackson knew whose DNA was picked, the King of Pop worked with fertility doctors to produce the kids through top-class genetic engineering labs.

The family aide insisted that Jackson`s former wife Debbie Rowe carried the fertilised embryos for him after the eggs were artificially inseminated in a lab.

The source, who has known Jackson and his family for over 20 years, said that Jackson saw himself as the father of the creation of his kids, but is not medically their father.

The source asserted that Jackson had this dream that his children should be from the greatest genetics and he was adamant that they came from intelligent, respected, healthy genes.

The insider said that Jacksons drug problems also played a major role as he knew his sperm may be damaged and once he made his decisions he locked the results in a safety deposit box.

Rowe gave birth to Jackson`s children Prince Michael , 16, and Paris, 15 and Blanket, 11, was born to another surrogate mother who had no idea that Jackson was to be the "dad".
