We've learned Michael Jackson was not the biological father of any of his children. And Debbie Rowe is not the biological mother of the two kids she bore for Michael. All three children were conceived in vitro -- outside the womb.

Multiple sources deeply connected to the births tell us Michael was not the sperm donor for any of his kids. Debbie's eggs were not used. She was merely the surrogate, and paid well for her services in the births of Michael Jr. and Paris.

In the case of Prince Michael II (the youngest), we're told the surrogate was never told of the identity of the "receiving parent" -- Michael Jackson. Three days after Prince was born at Grossmont Hospital in San Diego County, Jackson's lawyer came to the hospital to pick the baby up and deliver him to Michael.

We do not know if Jackson chose the sperm or egg donors or if he even knew who they were.

Although Rowe is not the biological mother, it's not a slam dunk that she would lose a custody battle. This type of case has never been litigated in California courts. Since Rowe was married to Jackson when Michael Jr. and Paris were born, there's a presumption that she's the biological parent. That presumption can be rebutted by other evidence.

We know there are documents outlining the whole arrangement for the birth of all three kids. Nonetheless, it's still an open issue with the courts.

We've just learned Michael Jackson's body is set to be driven to Neverland Ranch late Thursday morning.

Law enforcement sources tell TMZ upwards of a 30 car motorcade -- including Jackson's body -- will be traveling from Los Angeles to Neverland at 10 AM on Thursday.

We're told law enforcement is currently meeting to discuss security and traffic control. Our sources say plans are in the works for a public viewing to take place on either Friday or Saturday.

Story developing...

We've learned Michael Jackson never adopted his three children, even though he's not the biological father.

We broke the story that neither Jackson nor Debbie Rowe are the biological parents of Michael Jr. and Paris. And Michael was not the biological parent of Prince Michael II either.

Now here's the rub. We've learned Jackson never filed legal papers to adopt any of his children. Legal experts tell us Jackson would be presumed the father but it's not conclusive by any means.

As for why Jackson didn't formally adopt -- we're told at the time the kids were born there was no third party whom he believed would try and claim custody. For some reason, Jackson never thought Debbie Rowe would mount a custody challenge.

Over 20 never-before-seen pictures of Michael Jackson have emerged showing him as he lived his everyday life.

From birthday to costume parties, these pictures show a candid, unmasked, genuinely happy Michael as he interacts with his children, employees and friends.

Ever since the passing of The King Of Pop, the public response has been incredible. Check out the pictures of those affected by the death of Michael Jackson.

Just two days before he died, Michael Jackson practiced his moves during a rehearsal at Staples Center in L.A. for the London concerts.

Michael Jackson bought some pretty expensive art two weeks before he died.

On June 11, Jackson purchased a picture of the Wicked Witch of the West, a painting called "The Donut Queen," and a painting called "Play Ball." The artist for all three works was Nelson De La Nuez. Jackson plunked down $13,000 for the three items, which were delivered to his home on June 15.

We're told Jackson was "obsessed" with the Wicked Witch painting.
