Lady Gaga said she was quite surprised when Madonna started performing a bit of 'Born This Way' on her MDNA tour.
"I have to be really honest, I was completely kind of floored that Madonna was singing my song on her stage every night," she told Attitude magazine (as quoted here).
"I'm certainly not thinking about anybody but me and my fans when I'm on stage," she continued. "The fact that I was on her mind at all. I mean, Madonna's… she's Madonna."
Using past tense, she went on: "I looked up to her for a long time. I'm not quite sure what her intention was — to do that in the show — but I don't really care."
"I think playing into the gossip of the tabloids and, I guess the fodder of the competition, that's just not what I'm about. She chooses to use her voice the way she chooses to use hers and I choose to use mine the way I use mine."
So there's that.
