Selena Gomez and Justin Bieber broke up in November of last year, and ever since, they've tried several times to get back together. But after the most recent break-up, it appears the two are finally done for good. Selena took the stage at a private concert for Unicef and sang the same song that Justin randomly played right after their first break. What song is that? Justin Timberlake's "Cry Me A River"... and we all remember what that was about!
