The feud between Madonna and Lady Gaga is heating up.
Madonna has long claimed that "Born This Way" sounds shockingly similar to "Express Yourself" and she made her point on-stage.
Madonna ended the mash-up referring directly to Gaga, singing, "She's not me."
And now, Gaga, who is 27 years younger than Madonna, is responding. The pop diva let loose at a concert in New Zealand.
Gaga said, "It sometimes makes other people feel better about themselves, you know, to put other people down, or make fun of them, or make mockery of their work. I learned a lot about people trying to tear you down. I'm just not that person and I never will be."
Gaga is also letting her fans know that she's recovering after being hit in the head with a pole during an earlier concert. She tweeted a picture of her black eye and bruised face and said, "I feel a bit woozy but a little better everyday."
