You might think that it’s the young girls who go crazy for ‘Twilight’ and lead vampire Robert Pattinson. But as he told Davd Letterman last night, it’s actually the older women who are the more, uh, passionate type of fan.

Letterman doesn’t understand this because from his experience, women always scream when they see a bat. Clearly Dave is not a ‘Twilight’ fan.

The new ‘Twilight’ movie, ‘The Twilight Saga: Breaking Dawn – Part One,’ opens on November 18. Check out Pattinson’s take on his rabid fanbase below.
