Kristine Stewart is said to swear like hell in the set of “Breaking Dawn”, especially when she forgets her lines. An on-set source tells E! Online always drops the F-bombs and the crew has to be careful not to film those swearing to save it from leaking to the public. She swears out of frustration as she is taking the film seriously. The movie has been keeping secrets on what’s happening on the set, and this kind of attitude from Stewart is something that is not worth coming out. We know she wants to be taken seriously, but Stewart ought to watch her mouth or people will never take her seriously with that kind of mouth.
