Ke$ha had a cheeky treat for fans last night when she shared a nearly naked photo to Instagram ahead of a concert.

The Tik Tok singer stripped off for a backstage snap uploaded on Sunday night, showing her lying topless with a grey towel wrapped around the lower half of her body.

faKe$ha kept her modesty protected by covering her breasts with her hands, while pouting for the camera.

She added the caption: “Pre show. Let’s go.”

Fans were quick to compliment the popstar’s photo, with thousands liking the snap and hundreds leaving complimentary messages.

“You’re a piece of art come to life,” wrote one admirer.

“Beautiful and gorgeous,” wrote another.

fgKe$ha – real name Kesha Rose Sebert – was performing with her band The Creepies at the Brockport Student Government Spring Concert in Brockport, New York.

After the show, she returned to Instagram – still not fully dressed! – to thank the audience for their support and love.

“Thanks for tonight creeps and animals,” she wrote alongside a snap of her looking serene and happy. “So much love and wild energy packed into one room is so overwhelmingly magical.

dh“So grateful for my fans.”

Ke$ha – who has been locked in a court battle to leave her record label and release new music elsewhere – unveiled her new project, Ke$ha and the Creepies, last year

“This project and upcoming tour comes from my deep eternal love of dirty rock & roll and country music,” she said.

“I thrive from making and performing music, and much like a flower with no sun, my soul slowly dies when I don’t get to create and perform.

“So, for a short ride and in mostly small intimate venues, I will be performing a new creepy creation. It’s been too long.

“Until I can release my own music I will be reinventing some of my old songs and some of my favorite songs from my musical idols. I’ve hand picked songs from artists that have helped shape who I am and the music I make today.

“I have missed you, all of you, so if you would like to boogie, come join us.

“The time has come to get creepy.”
