The "We Can't Stop" singer along with Demi Moore and Bruce Willis' youngest daughters, Scout and Tallulah Willis, all struck NSFW poses to fight back against Instagram's rule that women cannot show their breasts on the photo-sharing site.
Miley and Scout both flashed their breasts but censored the image with strategically placed stars so as to not have the photo removed by Instagram. Meanwhile, Tallulah is seen propped on a table on all fours sticking her butt out. Scout, 23, gestures as if she's about to spank her sibling. "Lazzzzz night," Miley captioned the racy photo.
Tallulah, 21, and the former Hannah Montana star then took their photo shoot the the bathroom. "@buuski bathroom selfie," Miley captioned.
The 22-year-old singer couldn't stop flashing the camera. Posing in a black blazer while revealing her breast, she wrote: "ItZzzzz a Photoshoot."
Scout and Miley are among several stars who are supporting the Free the Nipple movement. ET got the naked truth on the campaign that's also supported by Lena Dunham and Chelsea Handler. Check out our coverage, below.
