Antifreeze Problem

Today when i stopped to get gas I saw that smoke was coming out of the hood of my car. I immediately got in and checked the temp gauge and it was in between the O and the R on Normal.

I then opened the hood and there was antifreeze on the top of the engine and it was leaking onto the ground. I checked the overflow to make sure it was full and it was pretty close.

I don't know if this is the headgasket or what but does anyone have an idea?

I haven't seen any white smoke. Well there was a little bit but it was more of a blackish color but that was about a month ago and I haven't had any problems since. Anyone have an idea?

could it just be a hose or something?

heres the one pic I took:



Thanks,

Ok thanks guys. I was told by a few other people that its probably the water pump
