strange noise???

When i drive my Clio i get a strange noise like here is a stone stuck in my tyre and the faster i go the quicker the noise gets. Now before you say it yes i have checked all the tyres and nothing in them. The noise is coming from the drivers side front wheel i think sounds like a deep clicking noise i jacked the car up and spun the wheels didn't hear anything but when i drive you can hear it like it only does it when its under heavy load it would be a wheel bearing would it???? any1 had same problem or knows what it could be????? cheers guys
 
drivers side is also the side with the longer driveshaft that is supported by a support bearing....could be this thats clicking and on its way out
