Jacob's campaign is being used to raise money for New York University's Skin Cancer Institute and other celebrities that have taken part include Spice Girls' Victoria Beckham, Dita Von Teese, Heidi Klum, Miranda Kerr, Naomi Campbell, and Bar Refaeli.

Cyrus posted her nude photo for the campaign on her Twitter account last Thursday. The photo shows her hands covering her private area and the campaign slogan "protect the skin you're in" obscures her chest.
