Selena Gomez And Andy Samberg Sink Their Teeth Into After Hours

It's sort of an unwritten rule that if you play a vampire in a movie, you have to know everything about the mythical creature, which explains why MTV News' Josh Horowitz has a few questions for Andy Samberg and Selena Gomez in the latest After Hours.

Promoting their new film, "Hotel Transylvania," the duo hit on many vampire-related topics like drinking blood, the "Twilight" series, general sexiness, and even why Justin Bieber hasn't really aged at all.

You can watch the brand new episode of After Hours above, and you can see "Hotel Transylvania" in theaters on September 28.
