Kristen Stewart and Rupert Sanders
Team Edward? Team Jacob? At the end of the day, Kristen Stewart wound up being Team Rupert. In a shocking turn of events, after over four years of dating Twilight co-star Robert Pattinson, it was revealed that Kristen Stewart cheated on the British star with her Snow White & the Huntsman director, Rupert Sanders. And to make matters worse, not only is Sanders nearly 20 years older than Stewart, but he's also a married man. She has since gotten back together with Pattinson.
