But at the time of filming it stated she was not to die on screen :).
tobefearfulofthenight: Do you think Kirby could have survived Scream 4? I think it's interesting that she's one of the only characters that isn't lingered on long enough for us to see the light leave her eyes, so to speak. We see her get stabbed, but never actually see her stop breathing.
She is most probably alive. Her contract stated that she was not to die on screen.
