HARRY POTTER star Daniel Radcliffe is still struggling to translate his fame into success with the opposite sex, because girls are still unimpressed by his attempts to start conversations.

The 16-year-old actor has learned that it is the person underneath the big screen exterior that really matters, and Radcliffe refuses to give up on his quest to secure himself a girlfriend until he is successful.

He says, "I'm much more confident (than Potter) but I'm just as rubbish.

"It's weird. I like to think that I'm not, but I may be wrong. Ask the girls. I don't have a girlfriend, but I try.

"I think of the perfect lines afterwards. I find that lines - no one should use lines with girls - don't work.

"'Hey, do you come here often?' What is that? 'Hey, is this seat empty?', 'Yes, and this one will be, too, if you don't leave me alone.'

"So I don't understand girls but I'm learning slowly."
