But it's not all backstage shenanigans and groupie love. When MTV News sat down with the "Blow" singer in New York earlier this week before her gig at Roseland Ballroom, Ke$ha said that amid the nightly onstage parties there have also been some poignant moments on her first headlining outing.
"Best moment? There are so many. Every night's amazing. I have kids outside right now chanting my name and it's awesome," she said of the first leg of the tour. "There was one night a fan came onstage, I invited him onstage, and he had a tattoo of the dollar sign. I was like, 'Oh, that's awesome! Badass. You're part of the cult, man.' "
And then, she said, he began to cry and explained that he was able to come out of the closet to his friends and family thanks to her song "Animal."
"And I'm standing onstage about to sing a song about growing back a pair of testicles ["Grow a Pear"] and I had tears rolling down my face and chills all over my body," she said. "Because that's really the reason I do music, to inspire people to be themselves."
Ke$ha has been a vocal supporter of the "It Gets Better" video project, which aims to help gay, bisexual and transgender youth find hope in the face of teasing and bullying.
The "Get $leazy" juggernaut continues on Saturday night with a show at Clarion University in Clarion, Pennsylvania.
