The reported tiff between CNBC's Money Honey Maria Bartiromo and upstart Erin Burnett, whom the New York Post dubbed the "Street Sweetie,'' is mana from heaven for News Corp. (NYSE: NWS) Chief Executive Rupert Murdoch.

His Post gets a juicy chick fight to write about -- although the General Electric Co. (NYSE: GE) cable channel denies there is a fight -- and it makes a rival to his yet-to-be launched Fox Business Channel look foolish as a bonus. Plus, it gives Fox a good excuse to try and lure either one of them away from CNBC. Interesting how corporate synergies work in today's media world.

Mind you, I have no idea whether Bartiromo and Burnett hate each other or not. Usually, Page Six is pretty truthy in the Stephen Colbert sense of the word. You have to think that someone close to Bartiromo or Burnett -- perhaps the person who looks back at them in the mirror -- is spilling their guts to the Post. Yes, the media world is just like high school.

Bartiromo has long been a subject of the gossip pages. I urged CNBC to fire Bartiromo earlier this year after her relationship with ousted Citigroup Inc. (NYSE: C) executive Todd Thompson brought derision on the network. Since then, she's indicated that she's more interested in being a TV star than a journalist. Burnett, whose path I crossed when I was at Bloomberg News, is gaining the good kind of publicity. In fact, Broadcasting and Cable called her CNBC's "secret weapon."

But there's an extra dimension to this tabloid battle that's worth considering.

There are many media conspiracy theorists who argue that Rupert Murdoch will tabloid up the Wall Street Journal once he gets a hold of Dow Jones & Co. (NYSE: DJ). I think that these fears are overblown. Murdoch won't use the Journal to settle scores with his enemies and heap praise on his friends. Why should he when the Post does that so well?
