"Dear Instagram trolls, body shamers, and the men and woman who think it's ok to comment on my weight: I hope that you don't have children. And if you do, I hope you teach them about kindness and acceptance," she began the heated post.
"Maybe you can't get it through your thick f**king skull, but nursing a baby for a year (and pumping in a van between takes, in the dead of summer in Georgia) is a lot of work, determination, and scheduling," Masterson explained. "So before you decide to make a comment about my chest being 'too large' or how 'fat' I've become, just know that this little girl got the best start to life."
"Also, grow the f**k up," she continued. "I would LOVE to see any man or woman give birth to a baby, nurse the baby, and then work 17 hour days and NAIL their own stunts."
