Bradley Cooper Joined Lady Gaga On Stage In Vegas, And They Sang “Shallow”

Last night, fans at Lady Gaga’s show in Vegas got a HUGE surprise. Bradley Cooper came out and joined her on stage. 

AND THEY PERFORMED THEIR SMASH FROM “A STAR IS BORN”!!! 

And it was AMAZING. 

I wish these two would do a live concert touring together, performing all the songs on the soundtrack. 

I would buy tickets to EVERY show and travel the country!!!
