Daniel Radcliffe is convinced Hollywood celebrities inform paparazzi of their whereabouts - because he rarely has problems with photographers trailing him.
The Harry Potter star slips into movie theatres and shops without fans recognising him - and can recall every time he has met a snapper on the street since becoming famous.
And the actor, who turns 20 on Thursday (23Jul09), can't understand why his fellow A-listers complain about having their every move followed.
He tells Empire magazine, "I don't understand how people get recognised and turn up in (magazines) as often as they do. They must call them (snappers) up and tell them, otherwise I don't get it. I've had so few problems with paparazzi. I've probably had four incidents in all this time. If they don't know where you are then they're not there."
But Radcliffe insists he has no problems with Potter fanatics or photographers approaching him: "Some of my friends get annoyed about people coming up to me, but it's fine and perfectly normal. You just get used to the fame thing."
