In The Twilight Saga: Breaking Dawn - Part 2, the supernatural daughter of Bella (Kristen Stewart) and Edward (Robert Pattinson) triggers a major threat to destroy the vampire clan.
And, in a press interview to promote the film, Kristen had nothing but praise for Mackenzie Foy's performance in the role.
"Most kids that are attracted to the idea of being an actor are just like little attention-seeking weirdos, I find," says Stewart, who herself was a child star.
"But Mackenzie was so solid and steady. Nothing was ever about her, it was always about being a part of the group and wanting to help out and that's how I was when I was a kid.
