The cast members of the Twilight Saga have taken over Twitter in a big way! But how do you tell who's real and who's a total faker?Right now, the most actively tweet-happy cast member is the good doctor himself, Dr. Carlisle Cullen (Peter Facinelli). In fact, he even got costar Robert Pattison to join the fun when he reached one million followers:"Thanks a million. Here's Rob... Hi, it's Rob... My first and last tweet. My dad made me do it. (3:35 PM Sep 18th from Tweetie)"Awesome job, Dr. C!Meanwhile, Eclipse director David Slade keeps us on our toes with the amazing photos he takes during filming (Taylor Lautner's backflip, for instance). And Michael Sheen (Aro) takes us with him on train rides through Ireland and the customs line at LAX!Just for your reference, below is a list of ALL the confirmed Twitter addresses of the cast members. Log on and say hi today and don't get fooled by impostors!
