It's been revealed that a mysterious NEW ending to Breaking Dawn: Part 2 has been dreamed up by Stephenie Meyer and screenwriter Melissa Rosenberg.

Hold on to your seats Twi-fans!

That's right, the two crafty writers came up with a completely different finale to the book over dinner one night, and it's this ending that will be used in the film.

Exciting times ahead people, because it means we have no idea what will happen to beauty Bella and blood-thirsty Edward.

So, what did stars Robert Pattinson and Kristen Stewart think when they first read the script?

'I got to that part and was like, 'What?' And then I had to go back a page. It does it a serious justice,' R-Patz told Entertainment Weekly.

While according to Perezhilton.com, K-Stew loves the change of ending: "It's clearly made by someone who really cares. That's why Bill Condon is perfect. Thank God for him."

Twi-hards won't have long to wait to find out what happens with the film coming to Australian screens in November.

How do you think the film will end?
