LOS ANGELES, Calif. -- Kristen Stewart gets her heart broken as Bella in 'New Moon,' and the star said it's an emotion she could relate to. 'I've absolutely thought I've been sure of something and then been told that I was just dead wrong so I can totally relate to that,' Kristen told Access Hollywood's Shaun Robinson of a past real-life break-up at the 'New Moon' junket in Los Angeles on Friday.
