Kristen wasn’t running around playing pranks on the ‘Breaking Dawn Part 2′ set! In a new interview her onscreen daughter Mackenzie Foy reveals what it was like to work with K-Stew!

Kristen Stewart means business. The actress isn’t a jokester like her boyfriend Robert Pattinson, she’s actually super focused. Her onscreen daughter Mackenzie Foy, who plays her half-vampire daughter Renesmee, tells Teen Vogue what Kristen is really like in person!

“Kristen is an incredibly hard worker,” she says. “And Rob is a big goofball.”

We told you that she said Rob was a jokester on the set, which we love to hear. We can’t wait to see this all play out when the final film hits theaters on Nov. 16!
