In a world where social media exploits the hottness of girls who like to post naughty pictures of themselves, there can only be one to come out on top as the The Hot Twitter Girl of the Week.  OK, so several can, but this week's honor goes to  Stephanie Ann Cook.

Stephanie is a Las Vegas hottie that not only models, but is involved with MMA, and is the spokesmodel for a non profit organization in Vegas that helps cancer patients called 'It Ain't Chemo'. So, she loves to help out people, digs fighting, and likes to post hot pictures of herself on her Twitter account.  What's not to like about her?

You can check out more on Stephanie on her Model Mayhem account, her Facebook fan page, and her personal Facebook page.

Enjoy this week's Hot Twitter Girl of the Week - Stephanie Ann Cook.
