Aside from the general pervy-ness of all us old men leering at a freshly 18 year old girl's undies, what gets me is that all the copy around those pics makes it sound like she flashed the camera or in some other way purposefully showed off.
It looks to me like she kept her legs together and her purse in her lap, like a young lady should. But if there are 20 guys with cameras crawling all over the car, one of them is going to get a view that none of us would if we were sitting across a table from her.
The way photographers are, all celebrities might as well get a payday from Playboy or Playgirl instead of waiting around for someone to catch their naughty bits elsewhere.
