Robert Pattinson & Kristen Stewart's Competition on Set: Who's The Better Vampire?

Even the most perfect of couples have something to fight about. This applies even to celebrities, including Kristen Stewart and Robert Pattinson.

The couple are both playing vampires in the "Twilight" saga's final installment, "Breaking Dawn part 2". And in a recent interview with an Italian magazine entitled Oggi, her main objective during filming was to become a better vampire than her boyfriend!

"I am a real vampire and I've tried to interpret it the best," said the 22-year old actress to Hollywood Life about how she tried to portray her role.

Kristen Stewart first made a name for herself in the 2002 suspense flick, "Panic Room", where she co-starred with Jodie Foster. Although she garnered mixed reviews for her choices of other roles, the biggest break she had was when she was informally screen tested on the set of "Adventureland" wherein she captivated the director, "Catherine Hardwicke". Although many critics continue to flak her as Bella in the "Twilight Saga", the final part of the saga might just prove otherwise.

"The challenge was precisely this. I'm sure that will put a strain on our relationship!" she continued jokingly about the "small debate".

The couple first met at the first "Twilight" movie, with issues about their relationship being a mere "publicity stunt" arising. The best thing about their said relationship is that even after years of criticisms from the media, they stayed strong together, perhaps lasting even after the Twilight saga is over.

As the finale to the Twilight saga, "Breaking Dawn, part 2" is very much anticipated by fans who call themselves Twihards. Even though the book spawned out four movies, it has continuously received mixed reviews much to the fans' sorrow. It has been repeatedly compared to different book adaptations, including "Harry Potter" and "The Hunger Games". In fact, it even created an erotic fan fiction that became a trilogy that is currently in the works of becoming a full feature film as well.

Whether Kristen succeeds in becoming the scarier vampire on set, fans will not have to wait that long until they judge them for themselves.
