She didn't accidentally tweet a nakey pic to Liam Hemsworth or anything but actually posed in the nude for fashion designer Marc Jacobs.
Don't worry, it's not really trashy or anything. She posed naked on a t-shirt for the designer for charity.
"Check out my @MarcJacobsIntl #ProtectTheSkinYoureIn tee❤❤❤We gonna save alot of lives #marcfam," she posted on Twitter along with the pic.
The t-shirts are available at various Marc Jacobs store locations and will be available in the U.K. next month.
What do you think of Miley's nude pic?
