Madonna too exhausted for the NRJ music awards

Madonna fuelled reports she is suffering from exhaustion when she failed to perform at the NRJ Music Awards in Cannes, France, on Saturday.

The Hung Up hitmaker, 47, withdrew from the prestigious awards ceremony on Friday - giving organisers an uncharacteristic one day's notice.

A source tells French publication Le Parisien: "She is exhausted. She rehearsed a lot of her routine for the video and she is on a strict diet to maintain her young and sexy image."

However, the singer's publicist Liz Rosenberg, insists Madonna is busy "filming her new video".
