Comic-Con 2012: Kristen Stewart on 'Breaking Dawn' sex scenes with Robert Pattinson
"We're supposed to have mind-boggling, other-worldly ... sex," Stewart says at Thursday's (July 12) press panel, loudly whispering the S-word with 11-year-old Mackenzie Foy (Renesmee) sitting just two seats down.
"Nothing about this series is raunchy," she continues, getting a surprised look from her co-star and real-life boyfriend Pattinson.
"Shut the f*** up," she says, ribbing Pattinson.

"We tried and they told us it was rated R," Stewart says of the sex scene they tried to make for the film. But her use of the F-bomb causes "Twilight" series author Stephanie Meyer to bring up the "swear jar" Foy had on-set -- if anyone swore in her presence, they had to make a deposit in the jar.
"How much money was in your swear jar at the end?" Meyer asks Foy.
"Do I have to say?" Foy asks, whispering the amount to Meyer.
"She never got a dime from me," Meyer says.
