Forget just showing some skin -- showing your butt seems to be the new thing in Hollywood.
Ke$ha's the latest star to follow the Miley Cyrus and Rihanna publicity route, by posting a ton of sexy "selfies" on her Instagram account over the weekend.
From pictures of her leaning against a wall with her backside just about fully exposed, to shots her showing some serious underboob, the "Crazy Kids" singer left very little to the imagination.
Guess we should be getting used to the whole showing-way-too-much thing -- what do you think of the 26-year-old's sexy "selfies"?
