Santa Maria- Put the doctor on hold – the ex-wife is coming to town!

This week, the prosecution is supposed to wrap up its child-molestation case against Michael Jackson, and on the state’s guest list is none other than the King of Pop’s second ex-wife, Debbie Rowe, the mother of his two eldest children.

She is a no-nonsense, Harley Davidson-riding woman who for years worked as the nurse at the office of Jackson’s favorite doctor, his dermatologist and plastic surgeon, Dr. Arnold Klein.

Rowe knows where the prescription-drug bodies are buried, she knows about Jackson’s deep desire to have his own kids, and she is on record as having declared that he should not be around children.

And, at this point in time, Debbie Rowe is mad!

Rowe hasn’t been allowed to see her children since Jackson was charged with child molesting, and she is currently locked in a closed-door custody battle with her ex in a Los Angeles family court.

District Attorney Tom Sneddon – who has been roundly criticized by reporters and talking-head pundits as having a weak case – will present Debbie Rowe as one of the prosecution’s strongest conspiracy witnesses.

Rowe is expected to testify about, among other things, the circumstances surrounding her appearance on the so-called rebuttal video Team Jackson sold for $3 million.

Under the confidentiality terms of her divorce agreement, Rowe had to promise to never – ever – speak or write about her ex. She agreed never to talk about paternity issues, Jackson’s mental or physical condition, his “sexual behavior” and lifestyle, his purported drug use and certain issues surrounding the location of the children.

So the very fact that Rowe appeared in that rebuttal video means that Jackson had to have given her his permission. That would place MJ smack in the middle of what the prosecution says was a conspiracy.

Suddenly, all those pundit declarations that the conspiracy portion of this case is weak become suspect.

But Rowe will not be the only strong conspiracy witness this week. The prosecution has built its case around the notion that Jackson agreed to let Brit Martin Bashir follow him around in the hope that the resulting documentary, “Living With Michael Jackson,” would boost his sagging career and faltering bottom line.

When the effect was exactly the opposite – when the world cringed at the sight of Jackson’s holding hands with his current accuser and declaring it perfectly normal to sleep with boys – the Jackson camp panicked, according to the prosecution, and promised a documentary of its own.

That documentary was to feature Rowe as well as the current boy accuser and his family, each saying beautiful, loving things about the pop idol.

But the boy’s mother proved to be a problem, and that, the state says, is when the strong-arm tactics began. The accuser’s mother testified here in court last week that when she and the kids were forced to participate in the filming, they followed a carefully prepared script.

But now here comes Debbie Rowe – and she is expected to tell the same tale, of having been ordered to follow a script prepared by some (if not all) of the unindicted co-conspirators. That’s exactly what Tom Sneddon promised in his opening statement.

But it turns out that Rowe doesn’t like to be told what to do any more than Jackson does – and now she has turned state’s witness.

If she wants to, Rowe could spill a lot of beans – because no matter what civil agreement of silence she signed in the past, it has been canceled out by the subpoena she received to testify in the criminal case.

She could turn out to be the type of witness who “volunteers” things during testimony.

And, oh, what tales she could tell!
