Tickets for the service at the Gibson Amphitheatre sold out within minutes, organizers said.The daughter of Mexican immigrants, Rivera was called the"Diva de la Banda." She sold about 15 million albums and earned a slew of Latin Grammy nominations during her 17-year career."Jenni made it OK for women to be who they are," her manager Pete Salgado said at the service. "Jenni also made it OK to be from nothing, with the hopes of being something."Rivera had five children, the first at age 15, and was married three times. Her third husband was baseball pitcher Esteban Loaiza. Rivera's private life influenced her songs, which often referenced living through hardship."She's a fighter and she knows it's in all of us," Rivera's son Michael said between video tributes.In recent years, Rivera branched out into television, appearing on a reality television show and serving as a judge on the Mexican version of the singing competition "The Voice."Television broadcaster ABC was reported to be developing a comedy pilot for the singer.Rivera's plane crashed in mountains south of Monterrey killing all seven on board.The singer was to perform in the city of Toluca, 40 miles (64 km) southwest of Mexico City, in central Mexico after a concert in Monterrey. It is not clear what caused the crash.
