What's black and white and red all over? "Page Six." That's right, we meant RED, not "read," because this morning the section was stained with blood, after further shots were fired in the intensifying battle between "Page Six"'s Paula Froelich and MSNBC's Keith Olbermann.

To recap! Last week, Froelich wrote an item in which she alleged MSNBC host Chris Matthews was talking loudly about taking over Tim Russert's job — at Russert's memorial service — and that he and Keith Olbermann had threatened to quit if he didn't get it.

Olbermann fired back by calling Paula Froelich "the Worst Person in the World" on his show.

Froelich responded by telling Gawker that Olbermann was "infantile" and "narcissistic" and saying that he suffered from "a severe case of malignant self-obsession."

Olbermann cleverly stayed quiet and allowed Froelich's actions to speak for themselves.

But Froelich could not take the eerie silence, and today lobbed a grenade into Olbermann's camp with an item about his behavior at the memorial service.

Olbermann was screaming into the phone … because there were no first-class train tickets ….Olbermann berated a staffer … [Olbermann] went apoplectic because there were no ketchup packets at the Kennedy Center.

It was the lede item and goes on and on, like the Tet offensive of gossip. But then, at the end, comes a perfect shot from the other side...

Oooh, Paula Froelich responded via Gawker to Keith Olbermann, who made her his "Worst Person in the World" last night after she wrote a mean item about him and Chris Matthews. According to Paula, Olbermann is "as infantile as he is narcissistic" and suffers from "a severe case of malignant self-obsession."

Oh. Really? Can't she do better than that? How about "His indignation is as believable as his snap-on hair," or "His whining reminds me of a constipated fox terrier." Or some such. Creative insults for both parties may be left in the comments. Let the real war of words begin!

No, You're the Worst Person In the World [Gawker]

So, last week, Wall Street Journal media reporter Sarah Ellison scored a deal to write a book for Houghton Mifflin about the News Corp. acquisition of The Wall Street Journal. Michael Wolff, who has been working on such a book, scheduled to come out next fall, is not amused. "The problem with someone from The Wall Street Journal writing a book is that they are inevitably conflicted," he told the Post today. When we e-mailed him this morning, he was a little more snarly. "Doesn't Sara Ellison work for the guy and for the company she's proposing to write a book about?" said Wolff, whose own book, a big-picture title about Rupert Murdoch and his career, is based on extensive interviews with Murdoch. Unlike Ellison, he said, who is taking a year off to write the book, but not actually leaving the Journal, his reporting won't be compromised by worrying about his next paycheck. "How exactly [will she] do that?" he said. Ellison did not respond to requests for comment, though presumably she'd say something like, "The same way I've been covering the Dow Jones takeover for the Journal since July." There is one other thing that is potentially awkward: Ellison's editor at Houghton Mifflin told the Observer some months ago that the book would have "new reporting," which seems odd, in the same way that it was kind of odd when Washington Post editor Bob Woodward kept the fact that he had known all about Valerie Plame quiet until State of Denial came out. Anyway, let's face it: These are not the most important questions. The most important question is this: Which one of these books is going to give us a reconstructed Rupert–Wendi sex scene? Yeah. Fight over that one.

Dueling Journal-ists [NYP]

New York's Fashion Week is over, and in the five minutes between the closing of the tents and the start of London's Fashion Week, all the stylish folks have had just enough time to focus on their distaste for one another. Seeing as industry-standard diet of clen and champers does little to help one's mood, we can't be surprised at this week's outpouring of bitchery. A quick rundown of the postshow battles:

Rachel Zoe vs. Anna Wintour
In Sunday’s Times' mag, stylist and possible "raisin-faced" alien Rachel Zoe unwisely taunts Anna Wintour: "Anna Wintour is one of my heroes, but they say I'm more influential," the stylist tells Lynn Hirschberg. "As great as it is, Vogue won’t change a designer’s business. But if an unknown brand is worn by a certain person in a tabloid, it will be the biggest designer within a week.” Oh no, she didn’t. But she did! And now let's follow the backbiting path over to…
