The tabloid newspaper, The Sun, has reported that actor Macaulay Culkin is the biological father of Michael Jackson’s youngest son, Prince Michael II, who is also known as Blanket.

According to an unnamed insider source, Culkin, who was a close friend of Jackson’s for many years, donated sperm to an unknown surrogate mother, and Blanket was born in 2002 when Culkin was 22 years old.

The source claimed, “It is well known Jackson and Macaulay shared a unique bond. Now rumors are spreading like wildfire that Macaulay, who Jackson nicknamed Mack, is actually Blanket’s biological dad.”

Macaulay Culkin and Michael Jackson first met in 1990 when Culkin was ten years old.

They formed a close friendship that lasted for many years.

The child star often visited Jackson at his Neverland ranch and even testified in his defense during Jackson’s 2005 trial for child molestation.

The two were so close that Jackson reportedly thought of using Culkin’s sperm to create a child.

According to the insider, “Michael is said to have idolized Macaulay, and thought using his sperm to create a child would be the ‘next best thing’ to being Macaulay’s father.”

The source added, “Deep down, I think he always wished Mack was his son. Creating Blanket was the next best thing.”

The Sun’s source claims that even Culkin himself suspects he may be Blanket’s biological father.

The insider stated, “This isn’t just chitter-chatter, even Culkin suspects he’s Blanket’s father.

“So many names have been mentioned as prospective dads, and this is probably the wackiest yet.

“But Jackson and Culkin were best friends. He was one of the few people Jackson really trusted, and Mack never let him down.

“Really, Jackson idolized him – that’s why he asked Mack to donate sperm.”

The report by The Sun also claims that friends of Michael Jackson believe he was not the biological father of his other two children, Prince Michael I and Paris.

The two children were born to Jackson’s ex-wife, Debbie Rowe, who was artificially inseminated.

Several men, including actor Mark Lester and Jackson’s dermatologist, Dr. Arnold Klein, have claimed to be the biological father of the children.

Mark Lester, who starred in the film Oliver!, has previously claimed that he donated sperm to Jackson in 1996, and could be the father of his children.

Lester has even stated that he would be willing to take a paternity test to prove his claim.

In a 2011 interview with the Daily Mail, Lester said, “I gave Michael my sperm so that he could have kids – and I believe Paris is my daughter.”

Dr. Arnold Klein, who was Michael Jackson’s dermatologist, has also been named as a possible father of Prince Michael I and Paris.

Klein was a close friend of Jackson’s, and the singer even named Klein as a co-guardian of his children in his will.

However, Klein has denied that he is the biological father of Jackson’s children, saying in a 2013 interview with TMZ, “To the best of my knowledge, I am not the father of these children.”
