Stephenie Meyer updated her site with photos from the set of Twilight the movie. Rumors were going around that she had lunch with the cast and this seems to confirm that. She has a very humorous post about the time she spent with the "people out of (her) imagination".
Also, the additional cast list was confirmed by Variety. Check it out.
Christian Serratos confirmed on her MySpace page that she will be playing Angela Webber. (Edited: A big "Hi" to Christian who mentioned that she visited our site.)
Thanks to TwilightObsessed for the photo line-up
