In the 2015 Metropolitan Museum of Art's Costume Institute gala, Selfies were banned.
As usual, celebrities never follow rules and the first one to break them was Justin Bieber.
The young singer snapped few pictures with his superstar friends.
But to be fair, after posing with Bieber, Delevingne and a whole bunch of other famous ladies piled into the bathroom to take selfies in the mirror like it was a high school prom.
Justin matched his Jacket covered with Golden Dragons with the gala's 2015 theme "China: Through the Look Glass"
