Ariel Winter underwent breast reduction because her large chest was making her "unhappy".
The Modern Family star - who turned 18 last month - underwent surgery to reduce her enormous F-cup boobs because of the effect her huge bust was having on her mental health.
Ariel insists she was never bothered by the negative comments she received about her figure online and her decision was made purely to please herself.
Writing an essay for Motto - a new website from the editors of Time - she revealed: "People may find it hard to believe, but when I got my breast-reduction surgery last year, it wasn't because of the mean comments online.
"It wasn't because I didn't like how I looked. Having so much weight on my frame was affecting me psychologically. I was uncomfortable and unhappy. I chose surgery because of how I felt, not because of what anyone else thought."
