If you're thinking you'll be seeing double with this trivia, you're right. It's actually 2 people who can be credited as the youngest producers ever. Mary-Kate and Ashley Olson were both only 6 when they began their producing careers. They are also the youngest self-made millionaires in American history, receiving millions by the age of 10 years old. By 17, they were said to have a total financial worth of $150 million. They are predicted to reach billions by the end of this year. Though many don't see them in the lime light any more, at least where film and t.v. are concerned, they seem to be raking in the money in the fashion industry.
Until they were older, there really wasn't much difference in the physical appearances of Mary-Kate and Ashley Olson. Later on, on Full House, however, they had to wear fake teeth because their teeth were beginning to look different. It seems that one has also gotten more press coverage for being thinner than the other actress as well. Ashley Olson has suffered bouts with anorexia on and off, but was last reported as practicing very healthy eating and exercising habits.
