Pop star KE$HA stunned her online fans on Thursday by sharing a nude photo of herself on Twitter.com.

The TiK ToK hitmaker was preparing for the MTV Video Music Awards in Los Angeles when she was caught on camera by a member of her entourage cleaning her teeth - with no clothes on.

Ke$ha protects her modesty by drawing her knees up to her chest and had no qualms about posting the image on the microblogging site.

In an accompanying post, she writes, "just naked brushing my teeth pre VMAs."

And she wasn't wearing much on the red carpet hours later, joking she wanted to "feel naked with a little bit of lace covering my bits". (CL/WNTWT/KL)
