Being a celebrity isn't always easy. For some, the stress can be overwhelming. 48 Hours reports on five famous people who have faced crisis and persevered. A duchess, a race-car driver, a comedian, a boxer and a model reveal that their success did not grant them immunity from adversity. But all are making their way back from misfortune and mistakes.
