In an MTV interview, Twilight star Robert Pattinson shared details about "The Twilight Saga: Breaking Dawn Part 1" particularly about his young co-star Mackenzie Foy who portrays the much talked about role of Renesmee Cullen, the daughter of Bella Swan and the vampire Edward Cullen.

"Mackenzie is great. She's really cool. She's really smart," Pattinson said before admitting that the 10-year-old has been making some extra money on set. Pattinson and Kristen Stewart hand over dough whenever they swear in front of their young co-star and according to the heartthrob, it happens a lot.

"She's got a lot of money out of us swearing around her," he revealed. "I do it by accident, and especially Kristen does it by accident, because she'll apologize with a swear word. 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," he laughed.

Pattinson went on to praise Foy's acting skills, revealing a few of the challenges she had to take on while playing a young vampire/human child.

"She's a great actress. She's really sweet," he said. "She has to do a hard part as well, because she's doing - I don't want to get into special-effects stuff - but she's playing a baby in some scenes," he said. "Oh, man, some of the stuff is so strange. I mean, we've done very strange things on the 'Breaking Dawn' shoot," Pattinson said with a laugh.

The first part of "Breaking Dawn" is tentatively scheduled for release on November 18, 2011. Twi-hard fans are going to be excited to watch the promising young star on the big screen as Renesmee Cullen.
