    Daniel Radcliffe, star of the Harry Potter films, says his love life is far from magic as he cannot find a girlfriend.
   

    Radcliffe, who is 20 next week, has thousands of adoring female fans around the world but is single.
   

    He told the reporters: "You know, I'm not really doing the dating thing, I don't feel like I'm in the world of dating. I don't feel like a young twentysomething.
