perez must be so pissed!

Tbh i didn't like the performance at all.

Absolutely AMAZING! They are both incredible. My favorite DWUW performance so far.

This happened and the world is a better place.

How to fill a stadium. Step 1 Gaga writes 10 new songs for 4 female singing parts. Step 2 Gaga performs duets with Xtina, Britney, and Katy. Step 3 Joint tour of Gaga, Xtina, Britney Spears, and Katy Perry. Bill as the 4 Queens tour, but unofficially it's the piss on you haters tour.

LEGENDARY QUEENS 😃

WONDERFUL! LOVE IT! ILY GAGA♥

#DWUW EPIC! youtube.com/...

best duett ever just omg just amazing perfect no words just speechless just kspfjdldbdpdn *______*

I honestly don't know why Gaga is still being called a flop and saying her career is going down hill. She just had major hip surgery what more do people want she has come back fighting her way back up to the top which most people couldn't of done after such a surgery. She's fucking amazing and I'm sorry but some people really need to have a close look at what they are calling a "flop" because she earned every bit to where she is now. She is one of the best singers and artists out there today and people really got to search up the meaning of music and sound if they think her performances are bad and career is going down hill. Gaga you are the definition of perfect and haters are wasting their time!

Ahhhhh they sound so great

I was so happy I ocould die when I saw them togather...
