From Twilighters Anonymous:
Tonight was the taping for Spike TV’s 2010 Scream Awards and not only did we have a few Twilight cast members in attendance, but they also presented and accepted a few awards! While we mentioned earlier that the ladies of Twilight – Kristen Stewart, Nikki Reed, and Ashley Greene – were scheduled to attend, Ashley had to cancel last minute and her onscreen beau, Jackson Rathbone, attended in her place.
