Come November 9th and the world could be in for another war, albeit a musical one.

As the world marks the 25th anniversary of the fall of the Berlin wall, you can see Madonna and Lady Gaga clash over the honor of performing in the anniversary event. Apparently, both the pop stars are duking it out to grab the coveted honor of performing exclusive in the show, with each refusing to play a second fiddle to another. It's all or nothing for the warring pop icons.

Says a source: “Madonna and Gaga are equally desperate for the honor of performing. They both like to think of themselves as very political, and will also have new albums to promote by then. It could reignite their long-running feud as the date draws nearer because neither are used to being told no.”

"However it's highly likely organisers would choose the Queen of Pop over Gaga, if push came to shove."
