Breaking the hearts of potential co-stars everywhere, Harry Potter star Daniel Radcliffe says he would never date an actress because they are “completely barking”.

Boy wizard Radcliffe, who turns 18 on July 23, said he mainly meets girls through his work, but some actresses were “just insane”.

In an interview to be published in the August issue of US men’s magazine Details, the boy wizard also reveals he is relieved the series is coming to an end.
