Lisa Ann

This may be year the last year Lisa Ann makes the "Dirty Dozen." In December, she announced her retirement as a performer. This is her second retirement, in fact. She started performing over 20 years ago, but stopped for a while to focus on the business side, running a talent agency.

So what's she giving up porn for? It's probably not what you think. In a handwritten note to fans, she said, "In my new life I dream of having an undefeated season in fantasy football while pursuing my career in fantasy sports." (She currently hosts a fantasy football show on Sirius.) She also plans to launch a new consulting company geared towards mentoring future performers.
