Justin Bieber released his fifth song since he kicked off Music Mondays and by the sounds of it, we’d bet some serious money that “Bad Day” is all about his ex Selena Gomez.

In the slowed down track, Bieber sings the details of a breakup, with lyrics like, “And that moment was so hard for me to breathe / ‘Cause you took away the biggest part of me, yeah / Life is so unpredictable.” Aw, poor Biebs!

While Justin may be singing about having a pretty bad day in his new song, his day didn’t get much better during a recent show in Brazil. The singer was left less than enthused after a water bottle was thrown at him at the end of his performance of “Boyfriend,” actually knocking the microphone out of his hand. Justin reacted by giving the bottle thrower a ticked off look and walking off stage.

Fans reportedly waited for almost an hour for Justin to kick off his show, but once the incident went down, he was totally over it.

“The public called for him, sang ‘Baby,’ and yet nothing,” a source told G7. “The lights came on, Bieber’s team started to take the equipment away and the fans realized it wasn’t going to happen. In the end there was no farewell, no thanks and no rendition of his most famous song.” Yikes!

Who knows the real reason for the bottle throwing (seeking attention or angry over his tardiness) but here’s a piece of advice: don’t throw items at the singers. It’s just not cool.
