Robert Pattinson and Kristen Stewart
For years, the Twilight stars refused to acknowledge their real-life romance. "So much of my life is so easily Googled," Stewart told British GQ in 2011, finally confirming their relationship. "I mean, it's like, 'Come on guys, it's so obvious!'" In July 2012, Us exclusively broke news that Stewart cheated on Pattinson with her Snow White and the Huntsman director Rupert Sanders, who was married to Vogue model Liberty Ross at the time. The costars officially split in May 2013.
