We've come across these new photos of the newest Twilight Saga cast member...

...Xavier Samuel. He is set to play the evil Riley, a hot college student and newborn vampire, who will go to great lengths to help Victoria murder Bella in the third film in the Twilight Saga series, Eclipse.

The 25-year-old Aussie was in Vancouver last weekend, attending the Eclipse pre-production sushi dinner and the Kings of Leon gig with his new castmates - sounds like he's settling in well! We came across these photographs of Xavier signing an autograph and having his photo taken with a Twilight fan on the way to visit an art gallery on Sunday - what a nice guy!

These photos got us thinking - is he a rival to Robert Pattinson in the Twilight Saga hottie stakes?
