Emotions were running very high at the MTV Video Music Awards on Sunday.
There were high highs -- when Taylor Swift and Nicki Minaj squashed their "Bad Blood" with an epic joint performance -- low lows -- when Minaj threw epic levels of shade at Miley Cyrus during her acceptance speech -- and WTFs -- when Justin Bieber began epically sobbing on-stage.
The Biebs delivered a spot-on performance of his summer hit, "Where Are U Now," and his latest single, "What Do You Mean?" -- even flying up into the air at one point -- but then he broke down in tears at the end of the set.
With no explanation at all, Bieber sobbed into his hands while a stunned crowd looked on. Naturally, all eyes were searching for Bieber's ex-girlfriend Selena Gomez, who was attending the show alongside her pal Taylor Swift and the "Bad Blood" squad.
So where was Gomez while all this was going down?
Gomez, along with Swift and the "Bad Blood" girls had exited the venue just before Bieber's set. So the world will never know how she might have reacted to those tears.

Earlier this month, Bieber opened up about having trust issues after going through hard times in the past.
"Trusting people is hard, especially for me. I've trusted people who I probably shouldn't have trusted before and they've hurt my heart," he said bluntly in an interview with Elvis Duran on his nationally syndicated radio show. "I'm a pretty sensitive guy, so I'll lay it all on the line, and they'll kind of pull it. So now I'm figuring out there's certain people I can't do that with."
