Justin Bieber covered "Cry Me a River" at his Saturday night concert in Boston, adding a bit more fuel to already broiling rumors that he and girlfriend Selena Gomez had broken up.

Though (as Vulture notes) Bieber has covered the Justin Timberlake track before, it does not appear on official set lists for his Believe Tour.

So, some questions: Was Bieber telling off Gomez? Is Bieber a clown? Is Gomez sad? Will Justin Timberlake ever make music again? When will Justin cover "Baby"? Is it really Monday already?
