Esquire, July 2007

Before she was mother to a brood of six kids, Angelina Jolie was known for her risqué ways. After she settled down with Brad Pitt, Angie still managed to spice things up when she appeared on the cover of Esquire magazine wearing nothing but a satin sheet. Even though she's (mostly) gone good, Angelina will always be a bit of a bad girl at heart.
