Heidi Klum showed off her fantastic figure in a new ad for the European cosmetic brand Astor, where she appears totally nude and covered only by elaborate body paint.

“I had another fun photo shoot for Astor celebrating color!” the 38-year-old Project Runway host tweeted, sharing the super-sexy photo with fans.

According to Klum’s blog, it took 12 hours for makeup artist Joanne Gair to perfect the intricate paint job.

“This was probably close to the 13th time I’ve been body painted by her,” she wrote. “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.”

It’s been a difficult few months for Klum, who split from husband Seal in January. The supermodel filed for divorce in early April and asked for joint legal custody of their kids – Leni, 7, Henry, 6, Johan, 5, and Lou, 2.

“Sometimes life throws you a curveball, and then you just figure it out and deal with it,” she told Allure last month of the break up. “But my dream always was that – to have the perfect family and have lots of children and a beautiful garden and trampolines and swings and things.”
