Ke$ha is famous for her so-called smoking hot outfits and her racy style on the red carpet and onstage. But it looks like she is ready to conquer the digital world by posting her "ultra-hot" pictures via Instagram.

On Sunday, the "Tik Tok" hitmaker went to Instagram and posted two rather sultry shots exposing her butt and under boob.

In the first picture, Ke$ha stood against a wall with her back arched and naked butt half exposed for the world to see, one can also see the black thong.

The singer titled the picture, "It's going down. I'm yelling #timber."

She had her hair tied up with a ponytail and was ready for the shots with dark eye makeup, clearly indicating that her fans and media can expect more in the near future.

Ke$ha wore a tight white t-shirt, a pair of socks and a red and white ghingham shirt and did the act with the sole objective of showing off her assets. She wore the shirt tight around her waist and tucked into her panties, thus exposing her butt cheek.

In the other photograph, she stared into the camera and gave the world a frontal view of her. In this one, she exposed her bosom which was hardly covered by the white t-shirt. She rolled the t-shirt up and flashed some under boob for the internet audience.

Apart from her racy photographs, her musical career hit a bump recently when the Australian leg of her tour with Pitbull got cancelled. "im so so bummed that our aussie tour was cancelled!! aussie animals, i love you very much and im working out how to come see you again asap (sic)!" obtained by Mirror.

Last week Ke$ha posted another bunch of semi-naked photographs on her Instagram page. [See the pictures, here]

Ke$ha is also in the business of fashion, her jewellery line called the Ke$ha Rose by Charles Albert collection was launched on Aug. 1 in the U.S.
