Kelly Clarkson’s official video to “Mr. Know It All” has just hit the web. It’s not the greatest of singles but it’s pretty good pop fare; the video is of a similar standard but it looks like they did manage to stretch the budget to a wind machine and peacock feathers, which is good enough for us. Enjoy it below, and preorder it on iTunes if you fancy it. “Mr. Know It All” is available 16th October.
