Most Infamous Moment: While she was married to Billy Bob Thornton, Jolie used to keep a tiny vial of the actor's blood on a chain and wear it as a necklace.

We knew Angelina Jolie was different than your average actress from the second we saw her, which was as a stark naked, lesbian model in 1998’s Gia. Since then Mrs. Pitt has admittedly frequented dominatrix clubs, boned Billy Bob Thornton in a limo while en route to an awards show and open mouth kissed her own brother at the 2000 Oscars. This isn't too much of a surprise, however, considering she grew up with a live-in boyfriend (whom her mother invited to live in their home) whom she would periodically get into knife fights with for pleasure.
