Kristen Stewart — sporting a retro Brigitte Bardot look — stopped by Late Night with Jimmy Fallon last night as part of her seemingly never-ending Breaking Dawn: Part 2 promotional tour. The usually stiff actress seemed at ease with Fallon (as opposed to her awkward chat with Jay Leno last week) while cracking jokes about baby Renesmee, Bella and Edward’s daughter in the film.

To capture the rapid growth of half-vampire-half-human Renesmee, director Bill Condon used a CGI baby in the film that Stewart likened to Chucky. “It’s got a lot of hair and sticky fingers,”  she said. Anytime Condon brought in an actual baby to play the role, Stewart said the cast was overjoyed. “Occasionally we did have a real baby and it was so clear. It was like reflected in everyone’s faces. The entire room would light up and then they would be like, okay let’s just try the digital one, let’s try the Chucky doll.” Can you say electronic baby drama?
