When she was still married to Billy Bob Thornton, Angelina Jolie posed half-naked for acclaimed photographer David LaChapelle with a horse, for a 2001 shoot for Rolling Stone magazine. Entitled “Horseplay,” the never-before-seen photo is up for auction in Christie’s fine art auction house’s The Wild Side of Photography sale in London. It’s expected to sell for anywhere from $30,000 and $53,000. The photo shows Angelina with a Billy Bob tattoo on one arm, while her necklace holding a vial of blood is hanging around the back of her neck. The horse’s teeth are a little close for comfort, but she doesn’t seem to be worried. Will you be bidding on this work of art?
