When Jolie and Billy Bob Thornton tied the knot, getting tattoos wasn’t the only thing the couple did to celebrate. The two also exchanged vials of each other’s blood. Jolie explains that it wasn’t a “vial,” but on inspection there definitely was blood inside the glass around her neck. According to The Sun article, Jolie even asked for five vials of her blood back from Billy Bob during their divorce so he couldn’t curse her.
