Heidi Klum Poses Naked For Astor CosmeticsGerman supermodel Heidi Klum has been the face of Astor cosmetics since 2010. Now Klum has stripped down for a new ad for Astor Cosmetics. The ad campaign celebrates the beauty line’s 60th anniversary.

Klum wrote on her site, “It took 12 hours for Joanne [makeup artist Joanne Gair]  to complete my look, but this actually wasn’t the first time she has painted me from head to toe. This was probably close to the 13th time I’ve been body painted by her, so I’m used to getting it done–the process takes awhile, so you have to be good at being patient! I don’t mind sitting still for such a long time though, it’s a living piece of art that I’m so honored to be a part of.” She adds, “However, I get so sad when the shoot is over because the beautiful paint all gets washed down the drain!”
