IPhone charger suddenly stopped working?

I was listening to music on my phone and charging it at the same time and right now its at 37% but 5 min ago i noticed it said that the battery wasn't charging anymore. This is the charger that I got with my 4s last year and I tried my very best not to bend the wire like I did to my multiple iPhone chargers in the past so there's nothing wrong with the wire. When I unplugged the wall adapter thing it was extremely hot so I unplugged it for a little. Why is it doing this?
