Harry Potter star Daniel Radcliffe is still starstruck when he meets J.K ROWLING, the author of the fantasy series. Despite having played Rowling's boy wizard creation on screen for the past six years - he confesses he is overwhelmed by the author's presence. Speaking at the U.K. premiere of Harry Potter and the Order of the Phoenix, Radcliffe says," I still get starstruck. When you're around her, you sort of sit there thinking, you know, I'll just be very professional about this, we're work colleagues now, but inside I'm just thinking, 'Oh my god, she's written the book!'"
