Jodelle Ferland (from last year's horror flick, Silent Hill) just tweeted that she has joined the cast of Eclipse. She tweets: "Oh by the way, the secret that I told everybody about yesterday is now all over the web so I may as well say it. I'm going to be in Eclipse!"
The 14-year-old Canadian will play a newly-created vampire that's terrorizing Seattle. Expect a tweet that she's in Vancouver soon - that's where the rest of the cast is meeting to film the third Twilight movie.
