Gosh golly geez, she's revealing it all on Instagram!
In the caption to the (above) naked snap, Miley confessed:
"shot by Karl Lagerfeld for @vmagazine #rebelissue"
The sinful pic features Miles covering her privates, while laying on a bed of stuffed animals! Not sure how that translates to rebellion, but we're sure Karl will explain himself when the rest of the pictures are revealed on September 10!
