Harry has a nude stalker

Harry Potter star Daniel Radcliffe has revealed he has a naked stalker.

The 13-year-old said: "I did an interview and we looked outside and there was a girl in a Harry Potter towel and nothing else at all.

"It was November in New York, so it was freezing. She was out there for 90 minutes holding a sign that said 'Nothing comes between me and Harry Potter'. Later I went to do the David Letterman show and she was there again, but this time she had clothes on.

"I got to say 'Hi', which was pretty cool."

However, Daniel's fame may come to an end - he has shot up eight inches since he was first cast as the child wizard.

This classic teenage growth spurt has fuelled speculation he is for the chop because he's getting too tall for his broomstick.

But it seems the world's most famous child star is here to stay.

In fact, sources at Warner Brothers say they would be keen for him to complete the series of seven movies, and are confident that with careful tending he won't become a hell-raiser like so many other child stars before him - and could be one of the great British actors of our time.

Daniel, now 13, commands £2 million a movie and gets about 1,000 fan letters a day. But, with his rocketing height, recently put at 5ft 4ins, breaking voice and soon-to-appear facial hair, starring as Harry past the third film had been looking increasingly shaky.

But David Heyman, producer of the first two films - the second, Chamber Of Secrets, is out next month - said: "His height is not an issue at all. He's just 13 and children do shoot up at that age. He's doing three definitely and then we'll see beyond that. Dan is a good enough actor that he'll be able to go well beyond Harry Potter."

Many people feared the young actor could soon be cast in the role of teenage tearaway. Macaulay Culkin amassed £25 million by the age of nine but sued his parents and refused to act for years. Drew Barrymore, child star of ET, was addicted to cocaine by 12.

But, thanks to efforts to protect him from the showbiz world, Daniel will not end up burned out at 15, said Mr Heyman, who will produce the next two Potter films, Prisoner Of Azkaban and Goblet Of Fire.

"When we cast the children, I and director Chris Columbus promised we would do our utmost to protect their private lives," he said. "Dan's parental situation is very stable and growing up in England is a good thing. Dan's life is regular. His parents deserve a lot of the credit.

"He meets schoolfriends. He goes to movies. By law, he has three hours of one-on-one tutorial a day. He's a great student. He doesn't get much pocket money, and blows it on DVDs and CDs, mainly punk rock."

Daniel himself confirmed that he's a dedicated punk rocker. He said: "I love original punk rock, like the Sex Pistols, the Undertones, New York Dolls, the Stranglers. Not so much the new stuff, although the Hives are good."
