Summit Entertainment say it's not.
Sorry Rob. Please don't let that hinder your love for us.
"There's some interesting and weird stuff going on - really very, very strange," says Rob.
"It's great. For a big mainstream movie, it's the most obscure storyline and really outside the box. It's a horrow movie.
"I've seen a few bits, and I just can't see how it's going to be a PG-13 - unless they cut everything out!"
Rob's also said in the past that he'd love it if Breaking Dawn was REALLY sexy and raunchy, the little saucepot.
"Can you imagine if they decided to go full out and Twilight suddenly became this totally hardcore series for adults with nude scenes?
"It would be funny."
So according to Rob, it's WELL SCARY, and has the potential to be a sex-fest.
Summit Entertainment have responded;
"Breaking Dawn will be a PG-13. It will not be Rated R."
Which kind of makes us want to go 'In your FACE ROB!' But we won't, because we're not mean like that, and a lower rating means more people can go and see it.
Although we wouldn't mind some extra sexy bits on the DVD.
What do you guys think?
