Daniel Radcliffe voices Robert Pattinson character in The Simpsons?

The Simpsons will be going all Twilighty for a Halloween special.

In the upcoming Halloween episode of the hit cartoon, Lisa Simpson will fall for Edmund the vampire – a character based on Robert Pattinson’s Twilight character Edward Cullen.

The character captures Mr Pattinson’s looks perfectly, however it won’t sound exactly like him. Rob won’t be voicing the character, so Harry Potter star Daniel Radcliffe has stepped in.

PerhapsĀ this is because Robert is a very busy boy at the moment. He has reportedly been spotted on no less than four dates with rumoured girlfriend and co-star Kristen Stewart in the past week.
