2. Ariel Winter
The Modern Family star was only 17 when she decided to have plastic surgery on her breasts. However, instead of going up like most girls, Ariel decided on breast reduction. She found that her breasts were so large that she was always being defined by them, and people were giving her negative attention because of them. Not to mention they caused back issues, so she made the decision to have them reduced to a more manageable size.
