Pop stars at war: Madonna, Lady Gaga fight over Berlin Wall

Pop stars Lady Gaga and Madonna are all set to reignite their feud as it is reported that they both want to perform at an upcoming show to mark the fall of the Berlin Wall.

The two pop superstars are both keen to sing at a special event on November 9, to commemorate the 25th anniversary of the historic collapse which united Germany, reports contactmusic.com.

"Madonna and Gaga are equally desperate for the honour of performing," said a source.

"They both like to think of themselves as very political, and will also have new albums to promote by then."

The pair have clashed in the past over the claims that the Applause hitmaker has copied Madonna's image.

"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," the source added.
