Fans are pretty sure they've already spotted her as a guest at the Swan-Cullen wedding. That's apparently Meyer on the left, seen standing up as Bella (Kristen Stewart) walks down the aisle.
Screenwriter Melissa Rosenberg and producer Wyck Godfrey also make brief appearances in the film, which opens Nov. 18. Meyer had an uncredited cameo in the first film of the series, 2008's 'Twilight' as a customer dining on a veggie burger in a scene with Bella and her dad (Billy Burke).
If you haven't already watched the 'Breaking Dawn' trailer 100 times, see it again after the jump.
