Úrsula Hilaria Celia de la Caridad Cruz Alfonso, known as Celia Cruz, was a Cuban singer and one of the most popular Latin artists of the 20th century. Cruz rose to fame in Cuba during the 1950s as a singer of guarachas, earning the nickname "La Guarachera de Cuba".
She does not have an Ordinary People Change the World book but she will appear in an Xavier Riddle and the Secret Museum episode, I Am Celia Cruz.
She is voiced by Ainsley Diaz.
Since she was met in Cuba in 1938, she would have been 13 when the trio met her.
