Lucy in Eclipse?

I do not know if this is confirmed or what is happening - Until I see it 100% from Twilight Lexicon or someone reliable like that I am hesitant to believe 100%

Also, I thought Jasper's back stories being filmed early on in production meant this part would have been cast and filmed but perhaps not?

According to BD Horror News Canadian actress Kirsten Prout has been cast to play the role of Lucy in the Twilight Saga – Eclipse. Kirsten is best known as Amanda Bloom in Kyle XY.

For those who do not recall who Lucy was, she served Maria (along with Nettie) helping her seek vengeance during the southern Vampire wars. Lucy and Nettie turned on Maria and were in return killed for doing so. Maria was Jasper’s maker, and this is told during Jasper’s back story (when explaining his story to Bella). Jasper describes Lucy as having “lovely and delicate voice” with “fair hair, and her skin was snow white.”

What do you think of their [alleged] choice for Lucy?
