Robert Pattinson & Kristen Stewart swear in front of screen daughter

Robert Pattinson and Kristen Stewart are always swearing in front of the young actress who plays their daughter in Breaking Dawn.

10-year-old Mackenzie Foy has been profiting from her dirty-mouthed co-stars.

“She’s got a lot of money out of us swearing around her,” Rob said during an interview with MTV.

“I do it by accident, and especially Kristen does it by accident, because she’ll apologize with a swear… She’s like, ‘Oh sh–! Ugh!’ She can’t stop doing it for about 15 minutes, and [Mackenzie] just waits there [with her hand out].”

Robert was also full of praise for his younger co-star.

“Mackenzie is great. She’s really cool. She’s really smart,” he said.
