"Dear @jackknife76. I see that you would very much like me to know that you think I'm ugly, and also a 'whore,'" she wrote. "Well, I understand that that is your opinion, but I disagree. I'm not perfect but I'm pretty f**king magical. and also, I am not, in fact, a whore."
"Also bullying someone who has struggled publicly with body issues is pretty mean," she continued. "Thank god I'm in a place in my life where I feel empowered to address your nasty comments instead of letting them destroy me."
"On behalf of anyone anywhere who struggles with body image, STOP IT.my body is not your business," she said. "In conclusion, kiss my magical imperfect ass!"
You go, girl!
Kesha took to Instagram just last month with a similar ‘f**k you’ message to her haters.
"I have been battling depression and an eating disorder for a while now," she wrote. "My career is in a strange place and it feels like I'm fighting an uphill fight some days. But I have decided to take my life back. My freedom. My happiness. My voice. My worth. I will not just f**king be quiet and hide. Today I will say f**k it and live."
Kesha sought treatment in 2014 for anorexia and bulimia, entering into a treatment facility where she spent two months.
"I'm a crusader for being yourself and loving yourself, but I've found it hard to practice,” she said in a statement to People at the time. “I'll be unavailable for the next 30 days, seeking treatment for my eating disorder ... to learn to love myself again, exactly as I am."
