American Eagle's lingerie model had a great response to a person who called her fat

Iskra Lawrence is not having any of the internet's fat-shaming.

The curvy model and newly appointed "role model" for American Eagle's wildly successful lingerie subsidiary, Iskra Lawrence, has fired back at one Instagrammer's comments, Next Shark (via Foodbeast) points out.

She specifically singled out one nasty commenter, and wrote, "I'm sorry I couldn't help myself...This is for anyone who has ever been called FAT. Thanks for the inspirational words on a recent pic @zseanzbrown," she wrote, highlighting the commenter. "Thanks to the dream team for making this happen at work today."

"Ps I do not condone binge eating," she clarified in the post. "I eat whatever I want in moderation. I will eat crisps but I'll also make healthy home cooked meals and workout regularly. The message is who gives a F what anyone else thinks of you. YOU are the only one who decides yourself worth. And sorry I'm usually not rude or give anyone the finger but these online trolls smdh. #iskralawrence #everyBODYisbeautiful."Aerie
