Mark David Kaplan knows how to get paid...

...and it sure as hell isn't going to be from his client K-Fed. Everyone's favorite legal baddass has filed a petition with the court. He wants Britney to pay for his legal fees to the sweet tune of $500,000 smackers. Considering Britney's experience with the courts I'm going to go out on a limb and say that the judge ordering Britney to pay is pretty much a done deal. Good one Kaplan, didn't see that one coming.
