So many girls just don't understand how bad tanning is for you skin... especially if you are natually fair skinned. It ages you drastically. Back in the day people used to rave about the California blond with a nice tan. I look and some of them now and yep, they have paid for it.
Jenna looks bit like Nicole Richie with a lip injection when she was anorexic
The anorexic look works well for some, like Kobe Tai and Heather Hunter, but not for others, Lindsey Lohan and Hillary Duff, for example look better with a bit of extra lard.
Who knows, may be it is intentional. I think she now wants to project an image of a "mature" business woman and may be even trying to move away from her previous wild pornstar look. Unfortunately, doesn't seem to work very well and she looks unnatural in these pics.
