In response, she posted a photo of herself in a swimsuit on Instagram, coupled with a strongly-worded caption.

Very very honored to be nominated for 2 Grammys and to be considered to play an important and evolving icon. Is it fat shaming if you know you're not fat and have zero shame in your game? I don't think so. I am strong and proud of how I live my life and say what I mean and fight for what I believe in and I have a blast doing it with the people I love. Where's the shame? It's not there. It's an illusion. When I look in the mirror I know who I am. Im a great friend, sister, daughter and girlfriend. I'm a badass comic headlining arenas all over the world and making tv and movies and writing books where I lay it all out there and I'm fearless like you can be. Thanks to everyone for the kind words and support and again my deepest sympathy goes out to the trolls who are in more pain than we will ever understand. I want to thank them for making it so evident that I am a great choice. It's that kind of response that let's you know something's wrong with our culture and we all need to work together to change it. Anyone who has ever been bullied or felt bad about yourself I am out there fighting for you, for us. And I want you to fight for yourself too! We need to laugh at the haters and sympathize with them. They can scream as loud as they want. We can't hear them because we are getting shit done. I am proud to lead by example. "I say if I'm beautiful, I say if I'm strong. You will not determine my story. I will" #thegirlwiththelowerbacktattoo

Schumer was scheduled to bring her comedy tour to New Zealand this month but cancelled her Australasian dates earlier this week due to illness. She's since apologised - but only to her Australian fans, posting on Instagram with a promise to reschedule as soon as possible.

Australia! I am so sorry I am not well enough to make it there right now. I am going to get healthy and come as soon as I can. I love it there so much. The people are the coolest and the meat pies are the hottest. See you ASAP!
