Chelsea footballer Didier Drogba will perform a version of 'Diamonds Are A Girl's Best Friend' at a HIV/AIDS charity concert.

The event, which is taking place at the Royal Albert Hall on September 23, will feature the Ivory Coast striker duetting with Lizzie Cundy on the track, which was once performed by Marilyn Monroe.

The soccer star, who has reportedly been backed by his teammates to go through with the performance, will be supported by 3,000 gospel singers at the show.

Cundy told The Sun: "It is very brave of him. He is opening a clinic in his name on the Ivory Coast to treat orphans with HIV/Aids. This cause means everything to him."
