Macaulay Culkin has denied the claims that he is the biological father of Michael Jackson's youngest son Prince Michael II.

The actor had been a close friend of the King of Pop for many years.

He was said to be angry when The Sun claimed he had donated sperm to the popstar.

The Home Alone star's Michelle Bega told TMZ: "The enquiries are too preposterous for us to even acknowledge."

Michael's seven-year-old son, nicknamed "Blanket", was believed to have been a result of artificial insemination from a surrogate mother.

The paternity of the popstar's other two children, Prince Michael who is twelve and 11-year-old Paris, has also been questioned with actor Mark Lester and dermatologist Dr Arnold Klein suggested as possible fathers.

Michael Jackson's death has been ruled as homicide by the Los Angeles Coroner's Office.

The singer was found to have lethal levels of the powerful anaesthetic propofol - as well as a cocktail of other drugs - in his blood when he died, according to court documents obtained by the Los Angeles Times.
