Looks like Justin Bieber and Selena Gomez' break up is becoming more and more dirty. We thought those two former teenage love birds would just be quiet about going separate ways, but that's really now how things went down. Selena recently sang Justin Timberlake's classic break up song "Cry Me A River" during a performance, and she told the audience that it "speaks to her". We think she performed it perfectly, but isn't it a little 2007 singing break up songs? Check out the video below!
