Ginger Lynn Allen is one of the biggest names to come out of the Porn Star industry in the early and mid 1980s. She's become something of a legend in her time. She attempted to go legit and move away from the porn industry toward cleaner films and actually acting. It didn't get her far, she went back to porn last year. (How do I know this...? Er... a secret informant...)
She also was thrown in jail for tax evasion but was later released.
