Actor Daniel Radcliffe is happy to be a serial monogamist - because dating multiple girls at once is too much of a "hassle".
The Harry Potter star has been romancing production assistant girlfriend Rosie Coker for almost two years and admits he's glad he no longer thinks of himself as a ladykiller.
He says, "I think for a while there I tried to date a few people at the same time - it's a nightmare! It's so much hassle. I couldn't keep up with it."
