First, Xavier Samuel. Now, Noot Seear.

The Twilight family continues to grow.

Seear, a Canadian model with no real acting experience, has been cast in New Moon. She'll play the role of Heidi, a villianess Volturi vampire who seduces human prey.

By the looks of her, this shouldn't be a problem.

Look out, humans. Noot Seear is out to seduce us all!

Said director Chris Weitz of the casting:

“We wanted someone who had an unearthly and unlikely beauty, but could also convey humor and menace. It’s rare to find a stunningly attractive person who also happens to have the ability to act.”

But is the model - who has posed for Calvin Klein and Alexander Wang, among other major brands - even familiar with the Twilight Saga?

"I started reading the books and I couldn't put them down," she said. "I've always been biting at the bit to get into the industry... what makes acting different is that you get a voice. You're not just a picture."

Based on her pictures, though, Kristen Stewart might need to worry. Will Robert Pattinson have the willpower to deny this beauty?
