The wailing you heard emanating from Taylor Swift's Tribeca apartment last Friday was not a cat trying to escape Taylor's rigid grasp, but Selena Gomez, who was crying because no one understands her. Not even her boyfriend understands her.

Us Weekly reports that at Taylor's 25th birthday party, Selena was seen "getting emotional" over her on-again, off-again BF Justin Bieber.

She shouted, "No one understands me! My boyfriend doesn't even understand me," an insider tells Us, adding that bystanders...just stared at her.

OMG Selena, there were a lot of famous bystanders at this party. Did Beyoncé see you crying? Eeep!

Another source tells Us that everyone besides Selena was having a "total blast," so that's good. Selena, Tayla would have killed you if you ruined her party.
