Spoiler alert: Bella gives birth in Breaking Dawn.
It's a pivotal scene in the arc of the Twilight Saga, introducing the world to Renesmee, Bella and Edward's half-vampire daughter (to be played by Mackenzie Foy) and Robert Pattinson finds it... hilarious?!?
"[Kristen] has to have this pregnant suit on all the time," the actor tells USA Today. "That was probably annoying for her."
Of course, Bella undergoes changes far beyond a baby bump, as well.
"I can't give too much away but there's some bits, especially towards the end of the movie, she's just like the polar opposite of any of the other (films)," Robert says. "I mean, she's a different person, which is cool. She looks completely different. She looks probably the most convincing vampire out of all of us."
As for the scene that truly has fans buzzing - hint! hint! - Pattinson says "there are some days on set just watching you go 'How is this going to be PG-13?' It's like totally ridiculous."
In other words: it's like totally hot and naked! Is it November 18 yet?!?
