SHOULD I APPROACH HIM OR WILL I JUST LOOK WEIRD AND PUT HIM OFF?

i am interested in this guy. i feel a bit embarrassed to admit this as i think it must look very strange but i saw a guys video blogs on my friends facebook page a few months ago. i find him really funny so i added him. A lot of what he talks about in his blogs i totally agree with, and his personality seems really cool.I find him really interesting. I wanted to approach him but there are a few problems. one i dont want to freak him out as dont know him and it will just seem very random. two he happens 2 be very attractive, i have noticed a lot of girls comment on his pictures and videos and he is also a singer/song writer so gets attention from all angles (but doesnt seem like a player at all), i wouldnt want to be unoriginal and just repeat the same things other girls have already said to him? i was trying to think of something different, i thought id sketch him (im an art student) and tag him but then i thought that would look very weird. i dont normally have this problem as i have never wanted to approach a guy before and i am normally the one thats approached, so im not familiar with it. is it a bad idea? are men suppose to be the "chasers"", will he think im desperate, or be put off? can you please give me some advice on what to do
