Kristen Stewart [1] may be a bit closed off in the public eye, but when it comes to her personal life and her work, she's an open book. The actress got candid with E! News [2] at the premiere of her film Equals at the Toronto International Film Festival on Sunday [3]. "I definitely wear my heart on my sleeve," Kristen said of her surprisingly emotional personality. "Sometimes that provides a little bit of a tougher road, but for me it's definitely more preferable." The star's raw interview references the upcoming sci-fi flick, in which she plays a human who lives in a world where people are stripped of their ability to have emotions. But she and her costar Nicholas Hoult discover they have a disease that allows them to feel, and they fall in love.

Kristen, who is currently dating Alicia Cargile [4], also admitted that the movie made her tap into past relationships. "It's first love," she said. "It's such a grand look at awakening. You take every first you ever had and you bottle it up in a moment and the devastating effect is something like anyone who has fallen in love at a young age has felt." While she said it wasn't easy filming certain scenes, she insisted that she wouldn't have it any other way. "That's the whole deal, man . . . The work that I'm most interested in, it always comes from a real place. Unless my heart is not in it, I don't understand why we're there. Every day that's led up to this day has made me who I am . . . Everything I have, I have put into this movie. Read into that what you will!"
