On October 28 2015, Katy Perry was the Unapologetic Bitch during the Los Angeles Rebel Heart Tour stop. Instead of giving Perry a standard banana, Madonna treated her to a banana flask filled with an alcoholic drink.
Later on Instagram, Madonna declared Katy to be the “Best Unapologetic bitch ever!”
Katy shared her videos of the experience on Instagram saying, “Well, that was unrehearsed but I Love You Madonna my QUEEN.”
Today In Madonna History 
I loved and enjoyed Rebel Heart! That was the best tour/album/era Madonna’s been involved with! She was happy, relaxed and friendly with the audience! I had the best time of my life!
That was the L.A. show that I went to!!! What a supreme “geek moment” for me to have the Queen of Pop and the Princesse of Pop on stage together! Can’t believe it’s already been a year!
