Kesha recently posted racy photos on Instagram in which she showed off her bare bum.

In one photo, Kesha was sprawled on the floor wearing a T-shirt with the phrase "High Fa$hion" written on it. The shirt also had an arrow pointing to her bottom. Kesha wore a thong and had her butt cheeks on full display.

In another picture, Kesha wore the same clothes and posed in a provocative manner. She captioned the photo, "butt."

The 26-year-old is no stranger to posting jaw-dropping photos. But, Kesha has made it clear she doesn't care what people have to say.

"I used [negative comments] to motivate me then, and I still do," she told Seventeen magazine in January. "I remember every person who told me I couldn't do something or that I was ugly or too fat. I have a 's--t list'-people from my past who have been soulless and judgmental."

She also told the magazine that she's the first person who will laugh at herself.

"I'm very much into making fun of myself because other people do it so you have to be able to laugh at yourself. The sooner you can laugh at yourself, the easier your life will be," she said.
