Erin Moran is a former child star best known for her role on the hit 1970s-1980s sitcom, Happy Days. Moran went from one of the hottest young TV stars in the early 1980s until Happy Days was cancelled, at which point her career completely derailed until she attempted an-ill advised comeback on Celebrity Fit Club: Boot Camp nearly 25 years later.
