"The Walking Dead" star Alanna Masterson works hard for the money, so you'd better "grow the f*ck up" and treat her right.

Masterson's character, Tara Chambler, just returned to the series in Season 7, Episode 6, "Swear." Tara and Heath left for a two-week supply run back in Season 6, but in real life Masterson was pregnant and needed time off for the November 2015 birth of her daughter.

Sadly, Tara's big return came with unwanted commentary on Masterson's post-baby body. She decided to fire back against everyone commenting on her weight in an epic NSFW Instagram blast:

"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. I hope they learn that it isn't ok to make fun of people or call people names. I hope one day YOU learn what it takes to be a parent. A kind, selfless parent. A working parent. A parent that puts themselves in someone else's shoes. Maybe you can't get it through your thick f*cking 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. 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. I wouldn't have changed it for a second. I would've gladly continued to eat enough calories to produce milk for her little bones to grow.

Also, grow the f*ck up. Your mother should be ashamed for raising such a judgmental bully. I'm sure she knows how 'courageous' you must be for trolling and hiding behind your Iphone and computers. P.s. 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. P.s.s. Be kind to each other. We need it now more than ever. ❤️✌🏼️"

You tell 'em! All of that came with this sweet photo:

"The Walking Dead" stars really do have it tougher than most actors -- shooting major action sequences outdoors from May to November, through the intense Georgia summers. Negan isn't the real Big Bad down there, it's the humidity. The stars deserve medals -- or, at the very least, empathy.
