"Twilight" fans, "True Blood" groupies, and "Buffy the Vampire Slayer" buffs, listen up: You owe Lourdes Leon, Madonna's daughter, a big thank you.

The pint-size Material Girl was seen walking around London yesterday with fangs. And no, the Brits don't celebrate Halloween a week earlier.

The vampire craze has bitten many of us, and celebs are no exception. We reported on Lady Gaga's fangs, and people getting fang implants, and even polled you lovely readers to ask your opinion on the trend.

It turns out, 7% of you have either thought about or already have fangs, and 11% of you do other things to display your vampire pride (like wearing dark nail polish or lipstick).

We can't wait to see the Halloween costumes you come up with this year!
