"I don't like people like that," Stewart told Entertainment Weekly at San Diego's Comic-Con in mid-July. "People who are a complete non-person but somehow through the lens seem like they are on and interesting and engaged. ... I don't want anyone leaving and saying, 'God, that girl is so fake.' "
She added: "People tell me to make it easier on myself and to play a character when I go out on carpets and stuff. But you know what? I'd rather be me."
Stewart was interviewed by EW while sitting next to Pattinson and their costar Taylor Lautner to promote the latest Twilight installment, Breaking Dawn: Part 2.
The magazine reports, "Nothing seemed amiss" and that the trio "were particularly relaxed."
About 10 days later, Stewart, 22, admitted to cheating on Robert Pattinson, 26 with her married Snow White and the Huntsman director.
