6. Naomi Campbell
When Mike Tyson describes someone as "afraid of nothing," then you shouldn't be surprised by her number of assault cases. Between 1998 and 2008, Campbell, who's notorious for her hot temper, was accused 10 times of committing violent acts against her employees, associates, and, once, a police officer. In 1999, Campbell entered rehab for her five-year addiction to cocaine.
While Campbell's reputation will always precede her, she's becoming well-respected for her charity work and for speaking out about discrimination.
