What is it with this surge in celebrities exposing themselves?

There was Britney Spears and now Jordan. There've been a couple others, but I couldn't find the links. For those who can't click on the links, basically these females are going sans underwear and sitting in cars with their legs open or at least with very short skirts. Of course the paparazzi love it and take the photos.

WARNING!!!1!!

ABSOLUTELY NSFW (NOT SAFE FOR WORK). GOT IT?
Now I provide these links for one reason only. I hate it when a story omits a picture when it is vital to the story, like that peace wreath thingie. So here and here they are.

Think the warning not to click was a little over-the-top? I just wanted to make sure you knew what was coming.
