I'm not defending Letterman. I am suggesting not to sell Bristol short just because her mother is Sarah barracuda.

To me it isn't whether she ever is fair game for the kind of sexualized humor comedians lavish on the likes of Britney Spears (who by the way was raised in Kentwood, LA pop 2,200).

Flash your private parts to paparazzi like she did and all demands for privacy and respect are off.

Ironically, here's a turnaround, Lynne Spears, Britney's mother, has now become a (very) minor celebrity in her own right: Pregnancy puts spotlight on Spears mom. She was goingto write a book about parenting until Britney's younger sister got pregnant.

Hmmm... expert on parenting.... sound familiar?
