Margaret O’Brien – Age 81

Margaret O’Brien got a taste of fame from a very young age, as she introduced herself to the world as a very talented child actress working for MGM. People noticed her from her first movie Journey of Margaret in 1942, and just two years later, she received the Juvenile Academy Award, a sign of how spectacular she was. Her good start ensured many lucrative roles for her afterward, and she must be having some pretty unique fitness routine to look so good in her early eighties.
