Kesha does not mince words.

The 29-year-old singer has been very open in recent years about her battles with eating disorders, depression and body image, including her time in rehab to address these demons. After so many struggles, including an on-going legal dispute with music producer Dr. Luke, it's no surprise that she feels empowered to take down the haters who’ve felt the need to comment on her appearance.

On Friday, Kesha called out a specific troll before launching into a lengthy message about self-worth.

"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."

The "True Colors" singer concluded by letting the world know that she doesn't need anyone else's unsolicited opinion about her booty -- and what haters can do to it. "On behalf of anyone anywhere who struggles with body image, STOP body is not your business," she said. "In conclusion, kiss my magical imperfect ass!"

Appropriately, this note was posted alongside a photo of Kesha bending over in the middle of picture-perfect blue waters, showing off said butt in a light blue swimsuit.

You go, girl!

This isn't the first time Kesha has opened up on Instagram. Last month, she also shared a defiant photo with her back to the camera and middle fingers up in the air while rocking a bikini, which included the sentiment, "a big ol' f**k u if u wanna hate on my body.'

"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 checked into a two-month treatment program in January 2014, and she has spoken candidly about her issues with anorexia and bulimia since leaving rehab.

In an interview with Vogue last year, the Nashville native explained that she "went to a dark place" before seeking help. "There was a lot of not eating -- and I started to think being hungry to the point of feeling almost faint was a positive thing," she told the magazine. "The worse it got, the more positive feedback I was getting."

Once she left rehab, Kesha focused on treating herself right, both physically and mentally. "I realized being healthy is the most important thing I can do for myself," she said. "Now, I'm trying to embrace the skin I'm in. It's difficult sometimes. Every day I have to look in the mirror and make the choice to be kind to myself. This is who I am -- I have to love that."

Telling off body shamers with bikini photos posted to Instagram seems to be Kesha's new go-to, as she also did the same thing in March. Find out more about that tell-off Instagram post in the video below.
