Estelle will be a special guest performer at the Art of Elysium's second annual New York City event tonight (April 30), replacing Florence and the Machine, who was originally scheduled to perform.

The Art of Elysium is an organization that encourages working actors, artists and musicians to dedicate their time and talent to children who are battling serious illnesses, either through personal visits or workshops in various artistic disciplines.

The event is hosted by Joy Bryant, Sara Moonves, Bee Shaffer and Nicole Vecchiarelli, and sponsored by Versace's Versus line.
