Why won't YouTube videos load on my iPhone 4s?

Since yesterday I've had the problem that when I go on the preinstalled YouTube app and try and play any video the video will not load at all and keeps pausing every 2 seconds. It's absolutely nothing to do with my Internet connection because my Wi-Fi is really good and I can get onto the Internet quickly. Also anything else that requires Internet on my iPhone runs fine. Anybody have any ideas why this is happening and what I can do to solve it?
