celeb stalking is a tricky art, first you need to find out when concerts or the like are on and it is guaranteed that they will be staying in a hotel near by.
however if they are not pop stars find out the area they live in (this will usually be on websites or in magazines)then if you are under 16 pursuaed your parents to take their next holiday there!
if all else fails dress in black hide behind trees (or do michael jackson and “climb trees” the mission impossible theme tune could also help.
so there you have it i hope that this comes in useful.
