We asked Liz Rosenberg about this discrepancy between what she said earlier, and what's happening now. Her answer: "there was no pending divorce earlier this year."

So, we asked, does that mean that, for example, the Sun's report that Madonna "initially planned to move back to the US with their three children in July" is false? "yes," Rosenberg replied.

Well, how credible is Liz Rosenberg? She told the world in 2006 that Madonna was not adopting a baby in Malawi. Although, of course, Madonna did adopt a baby in Malawi.

What else do we know about Rosenberg?

• According to CityFile, she's "best known for having served as Madonna's flack for more than 20 years. Other clients have included the Pretenders, Cher, Josh Groban, Stevie Nicks, Seal, k.d. Lang, and Liza Minnelli."
• She does a good job of staying friendly with celebrity magazine editors, naturally—she's allegedly been showering the editor of People with free Madonna tickets for a decade or more.
• She knows how to play hardball—she reportedly managed to silence a good deal of potential press coverage of Madonna's brother Christopher Ciccone's book last summer, which portrayed the singer negatively.

So Rosenberg does her job. Regardless, no matter how much wheedling, pleading, bargaining, threats, or doubletalk a flack uses, they're not supposed to flat-out lie. But Rosenberg has quite a reputation for lying. Look! Some of the most vehement "Rosenberg is a liar" voices are the most fervent Madonna fans, like commenters on AbsoluteMadonna.com. It might be advantageous to court them, from a PR point of view!

Celebrity flacks are probably the only remaining category of PR people who can get away with bald-faced lies, and continue to be effective in their jobs. Corporate flacks run the risk of pissing off business reporters (or even the SEC), which would make them liabilities. Media flacks? Lord, they have to be friends with reporters. To lie is to die. Despite the vague public perception that all flacks are liars, they really can't be if they want to have a long-term career.

Unless they have a client like Madonna! Because the celebrity media will want to cover Madonna for the rest of her natural life no matter what she or her flack does. So Liz Rosenberg, yes, probably finds it expedient to just lie and now and then, without any real consequences.

But that also means you shouldn't necessarily believe anything she says.

According to a tipster, Castro has been accepting free tickets to Madonna shows since at least the early 90s. Those tickets, of course, sell for exorbitant amounts, and can be scalped for even more—in all they add up to "thousands" in value, the tipster says. The most recent case, they say, was the Madonna show in New York that Yankee superstar A-Rod attended, and which is now the subject of great interest because of the rumored fling between the two.

And who is bestowing all these tickets on Castro? Reportedly it's Liz Rosenberg, Madonna's lying flack! You may also have noticed People's recent sappy and credulous coverage of the supposed strength of Madonna's marriage to Guy Ritchie. Our source says that the friendly Castro deliberately chose to overlook the A-Rod affair rumors and "play nice" with Madonna and Rosenberg.

But we're sure it was a coincidence. Have other info? Email us.

1. Liz Rosenberg: Lied about a poor African child, of all things. If she turns out to have lied about the divorce as well, she will only solidify her top spot here.

2. Stephen Huvane: Kirsten Dunst's rep assured everyone that Dunst was "fine," shortly before the actress checked into rehab. Then assured everyone that Dunst "is not being treated for cocaine or any drug." Yea.

3. Rob Shuter: A serial manipulator who invented a relationship between client Jessica Simpson and crooner John Mayer, which then blew up in his face. Now edits OK! magazine, appropriately.

4. Rachna Shah: The Interview magazine flack scolded us for printing a scurrilous rumor that editor Ingrid Sischy would be leaving the magazine. A rumor that turned out to be true. A conscious lie, or just internal miscommunication? Either way, we were right.

5. Edelman: An anonymous media trainer at the mega-firm was outed by a tipster for telling clients, "Sometimes you just have to stand up there and lie." This brought an angry response from CEO Richard Edelman, who has himself lied on behalf of Wal-Mart.

6. Scott McClellan: Rotund former Bush lap doggie who wrote a book being sad about all the lying he did. Not that the PR industry cares or anything.

7. Danielle Perissi: Time Warner's fibbingest flack. Not a good person to call with questions about Time Warner, oddly enough. Now she's gone.
