Singer/songwriter Alicia Keys attends the NBCUniversal 2016 Upfront Presentation on May 16, 2016 in New York, New York.

*Alicia Keys will take the unprecedented step of becoming the first artist to sing live at a Champions League final opening ceremony, where ten-time champions Real Madrid host city rivals Atletico Madrid at the Giuseppe Meazza stadium, commonly known as the San Siro.

An estimated global audience of 180 million people spread over 220 countries will watch the Spanish league giants lock horns in the final for the second time in three years.

Unlike the opening or closing ceremonies of the Olympics, the Champions League final has never featured a live performance.

Keys is set to sing three of her “biggest hits”, according to the ceremony organizers, but is expected to sing some of her new material when she is joined by 400 voluntary performers during a performance created by world famous events choreographer Wanda Rokicki.
