The one with Gaga is real and all the others are fake. Why tf would there be a huge ass bird obstructing people's view? And who tf is lying on the stage? It isn't very convincing to me.
I think it's fake, because on the third picture, from the right - the C-STAGE, supposed to have the stairs (that Gaga sits on, in her picture she posted) - so if these pictures are official, and made by Gaga and her team- it should've include it.
I REALLY HOPE ITS FAKE!! THE FIRST PIC WITH GAGA WITH HER LEG HANGING OF I HOPE THATS REAL BUT THE REST I HOPE ITS FAKE...WELL I GUESS THE PEGASUS IS REAL BUT THE SET FOR THE MAIN STAGE IS LAAAME COMPARED TO THE CONCEPT ART SO I AM REALLY REALLY HOPING A FREAKING ARCH WAS IS NOT THE SET FOR THE STAGE. GAGA CAN DO MUCH MORE THAN A FREAKING GREEK ARCHWAY...NO OFFENSE IF SOMEONE MADE THESE. I JUST GOT REALLY SAD BECAUSE I LOVED THE CONCEPT ART
