The 31-year-old singer is gearing up for a 30-date tour with Macklemore, entitled 'The Adventures of Kesha and Macklemore', and she's promised fans she won't be any ''less crazy'' at the shows as she is not feeling like a ''sad sap'' anymore.
Speaking to the June issue of the US edition of Cosmopolitan magazine, Kesha - who is in a relationship with Brad Ashenfelter - said: ''I've taken ownership of myself. I'm taking control of my life and my name and the music it's attached to. I'm not, like, a sad sap now. There are a couple of ballads, but my show is still extremely fun.
''I'm not going to be less crazy. There's an awesome band, and there's dancing and glitter. That's a promise I will keep - there will always be glitter.''
In 2014, Kesha accused the music producer of sexually abusing her, drugging her, and emotionally abusing her for years, but he profusely denied the claims.
In February 2016, Luke tweeted: ''I didn't rape Kesha and I have never had sex with her. Kesha and I were friends for many years and she was like my little sister.''
However, Kesha went on to release her third album 'Rainbow' last year, despite still being tied to Dr. Luke's label.
The 'Tik Tok' hitmaker was subsequently nominated for two Grammys in 2018, for Best Pop Vocal Performance and Best Pop Vocal Album for the record, which she used to channel the ''pain'' she felt throughout the difficult period in her life.
She explained: ''I would write, and pain would turn into art, and the art would turn into healing, and the healing turned into a record. And then I was nominated for a Grammy!''
Kesha also checked herself into a rehab clinic during that time as she was suffering with an eating disorder.
However, she now feels confident in her own skin and ''loves her junk'', something she didn't imagine to be possible.
She said: ''The final straw was when I was with my mom at a family dinner party and I was so anxious. Driving home, I had to pull over, and I was like, I can't keep this secret anymore. It was scary, but I finally put my foot down and chose life.
''That was a huge turning point.
''I'm not a size. I'm not a number. I am a strong, badass, motherf***ing woman, and quite frankly, I like my junk. 10 years ago, I never thought I'd be able to say that.''
