Robert Pattinson and Kristen Stewart pose with Mackenzie Foy on the cover of Entertainment Weekly‘s latest issue.

The 11-year-old actress plays Renesmee, the half-human, half-vampire baby of Bella (Stewart) and Edward (Pattinson) in The Twilight Saga: Breaking Dawn – Part 2, which hits theaters November 16.

“It’s a hugely important part. They were amazing with her. It really brought something paternal out in Rob, and Kristen was especially protective. I’d have to interrupt them when they were in deep conversatoin to get going with a scene,” director Bill Condon told the mag.

“[The Twilight cast is] all around the same age and we’re really not polite to each other anymore,” Rob shared. “You’d have to tone it down when Mackenzie was around … She had a little swear jar, and I think she made 850 bucks or something.”

As for working with her young co-star, Kristen said their “hands [even] look similar. It was kind of strange. But it’s funny how it actually helps. It’s like, ‘Oh, hey, you look like me, kid! Come on!’”
