In an interview with AFP, Colombian singer and pop star Shakira says that losing her voice "really was the darkest moment" of her life. The hemorrhage in her vocal cords forced her to postpone her international tour "El Dorado" for seven months. The star is now launching a film about that tour, "Shakira in concert: El Dorado World Tour", which is due to be screened in more than 2,000 cinemas in some 60 countries on November 13.
