It was the worst performance of the best song on The X Factor! It was really terrible, but SO catchy! As a matter of fact, it was so bad/good that Kelly Rowland, Demi Lovato, Simon Cowell and Paulina Rubio had to do a remake! Give it a listen and tell me if you don't get the worst earworm! The first video is the awful version done by the contestant duo and the second one is the good remake done by the judges. And guess what? I'm told Lafayette's own Holly Letchworth (who went to Acadiana High School and UL) is in the shot with Demi Lovato!
