(Photo by Joel Ryan/Invision/AP, File) (Newser) – A Twitter meltdown, a delayed show, an onstage fainting spell, a near-brawl with a photographer ... and now you can add a canceled concert to the growing pile of evidence Justin Bieber is losing it. The Biebs canceled tomorrow's concert in Portugal, and TMZ says it's because not enough tickets were sold. The gossip site calls the move "unusual" for a star of Bieber's stature. And that's not the only bad news for Bieber: All the gossip sites are speculating that Selena Gomez has a secret, not-so-pleasant message for her ex-boyfriend. Gomez released a video of herself and friends dancing to "Everybody Knows," a song by Dustin Tavella including the prominent lyric, "Your boyfriend is a douchebag / And everybody knows."
