Madonna Covers Lady Gaga's 'Born This Way,' Says 'She's Not Me' [VIDEO]

Many Madonna and Lady Gaga fans have noted the similarities between Madonna's hit Express Yourself and Lady Gaga's Born this Way, and now the Queen of Pop is merging the two songs to send out a message to Gaga: She's Not Me.

During a rehearsal for her MDNA tour in Tel Aviv, Madonna performed her 1998 classic Express Yourself, before breaking into a medley, merging with Gaga's Born this Way. But instead of celebrating Gaga's tune, Madonna took the opportunity to criticize the artist and clarify that she was in fact not her.

When I heard ['Born This Way'] on the radio, I said that sounds very familiar. It feels reductive, Madonna told 20/20 earlier this year. I certainly think she references me a lot in her work. Sometimes I think it's amusing and flattering and well done. It's a statement about taking something that was in the zeitgeist, you know, 20 years ago and turning it inside out and reinterpreting it. ... There's a lot of ways to look at it. I can't really be annoyed by it because, obviously, I've influenced her.

Meanwhile, Gaga, who is also on world tour at the moment, had to cancel a sold-out concert in Indonesia due to threats from Islamist groups who condemn her for her provocative dance moves and outfits.

One group described her performances as pornographic and called the artist a devil worshipper, according to the Christian Science Monitor.

This is part of the dilemma of the transition to democracy, Ulil Abshar Abdalla, head of the department for policy studies within Indonesia's ruling Democrat Party, told the Christian Science Monitor. On one hand we have phenomena of rising intolerance, and on the other hand we have a weak government unable to address this issue.

There is nothing Holy about hatred, Gaga wrote on Twitter, explaining the decision to her fans. We had to cancel the concert in Indonesia. I'm so very sorry to the fans & just as devastated as you if not more. You are everything to me.
