This is...actually kinda interesting and also a total mind f-bomb. Back in November (when Bieber and Selena broke up for the first time), Biebs covered Justin Timberlake's Cry Me A River (a song about breakups) during his show in Boston. Here's the video.

Fast forward a couple weeks ago, and Selena Gomez busted out THE SAME SONG during a benefit for UNICEF. Here's her performance.

1) So....they clearly hate each other, or do you think it's just publicity and they don't actually hate each other?

2) Who do you think sang it better? I'm actually leaning toward the Biebs...
