Bella (Kirsten Steward) is finally a vampire in Breaking Dawn part 2 following her marriage to Edward Cullen (Robert Pattinson) in last year's first Breaking Dawn entry.
Breaking Dawn - Part 2 sees the Cullens gather together various vampire clans to protect Edward and Bella's daughter Renesmee from the Volturi, led by Michael Sheen's Aro.
MyAnna Buring, who plays Dilani Tanya in Breaking Dawn - Part 2, says that Stewart makes a "stunning" vampire Bella in the last Twilight.
"[She's] gorgeous. It's bizarre, you couldn't think she'd get any more gorgeous, then she turns into a vampire and is even more stunning!" Buring said.
Taylor Lautner, Ashley Greene and Dakota Fanning co-star in the film, which will show in cinemas worldwide on November 16.
Twilight studio Lionsgate recently suggested that the movie series may continue after Breaking Dawn - Part 2, despite it being the final adaptation of Stephenie Meyer's novels.
It was also hinted that the books may be turned into a TV series.
