Late King of Pop Michael Jackson's long-time friend has dismissed rumours that he is the biological father of Prince Michael II, also called 'Blanket'.

Al Malnik, who also happens to be Blanket's godfather, has denied that he served as a sperm donor for the child, who was delivered by an unknown surrogate.

"It would be very interesting to realise that I didn't meet Blanket until he was two years old. So that wouldn't qualify as a rippling event I think. Of course I'm not the biological father," the Daily Star quoted Malnik as saying.

He also added that he would only continue to be a part of his godson's life "if it were court authorised or the Jackson family authorised it."
