The singer also recently got a whale shark tattoo.
Kesha opened up on Sunday about her battle with depression and an eating disorder, but the good news is the singer appears to be happier -- “happy as a damn clam," in fact.
The 29-year-old "True Colors" singer took to Instagram with a picture of her bare back to the camera and a defiant double fist raised to the 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," she continued. "Today I will say f**k it and live. So F*********K it. Today I'm making that choice. AND I'M HAPPY AS A DAMN CLAM. And also a big ol' f**k u if u wanna hate on my body. Just remember that makes u look like a dickhead."
Kesha followed up the post within hours with more photos of what appears to be a tropical vacaction, where the singer swam with whale sharks and also later sported a new tattoo of the huge-but-docile species.
"When a whale shark decides to be ur best friend and reconnect you to your true self and nature and spirituality and magic and beauty and love and gratitude.....I LOVE THIS WHALE SHARK. I CANT EVEN. #whalesharklife," she wrote.

The singer opened up about her eating disorder in an interview with Vogue last year. "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 said at the time. "The worse it got, the more positive feedback I was getting. Inside I was really unhappy, but outside, people were like, 'Wow, you look great.'"
More recently, Kesha has been facing an ugly and ongoing legal battle against her former producer, Dr. Luke, who she claims raped and drugged her. The music producer has denied all allegations.
