Somewhere in America Miley Cyrus is... posing nude. But it's not what you think. The 20-year-old pop singer is lending her naked body to a t-shirt campaign that will benefit skin cancer research at the New York University Cancer Institute and New York University Langone Medical Center.

The "Protect The Skin You're In" campaign has been able to draw celebrities like Kate Upton, Naomi Campbell, and Hilary Swank, all of whom stripped down to appear on the shirts. The t-shirts will be sold at various Marc Jacobs Boutiques across the country starting today and cost $35. Designer Marc Jacobs and his business partner Robert Duffy run the campaign.

Duffy said that he and Cyrus have been friends for a while now. "She is talented in many mediums from music to film," he said. "She really has a very good, solid head on her shoulders. I adore her."

Cyrus has been doing a great job of getting people's attention lately. She crashed the stage in a crop top and baggy jeans to perform Robin Thicke's hit song "Blurred Lines" at his concert last month. And, probably most infamously, she "twerked" on stage with rapper Juicy J as he performed an ode to strippers entitled "Bands A Make Her Dance." She's even the subject of a song on Jay-Z's new album, in which he repeats "somewhere in America, Miley Cyrus is twerking."
