Is Jenna Jameson Anorexic or Is Tito Ortiz Just Huge?

Pictures like this one of porn star Jenna Jameson and her mixed-martial arts fighter boyfriend Tito Ortiz have a lot of people concerned about Jameson's health. That low-cut dress exposes more than just cleavage. It also exposes her ribs, and there's growing talk that Jameson might have an eating disorder.

TMZ calls her half the width of Ortiz's arm. And while Ortiz is big, he's not that big; he's a light heavyweight.

Between the speculation about Jameson's health and Ortiz pulling out of a scheduled boxing match against Ultimate Fighting Championship president Dana White, it hasn't been a great couple of weeks for the celebrity couple.
