Watch our video as she says a few words and enters the tunnel at New York's Shea Stadium to see ex-husband Billy Joel perform one of his two-night send-offs to the home of the New York Mets. Special guests joining Billy on-stage at the sold-out shows were Aerosmith's Steven Tyler, Tony Bennett, Garth Brooks, Roger Daltrey, Sir Paul McCartney, John Mayer and John Mellencamp.
