Latin music superstar Luis Fonsi will serve as an official celebrity ambassador for the 6th Annual Thanks and Giving® campaign supporting St. Jude Children’s Research Hospital. Through televised spots to air in Spanish-language markets around the United States and Puerto Rico, the Latin pop music superstar - nominated for two Latin GRAMMY awards for Record of the Year and Song of the Year - will work to raise awareness of the Thanks and Giving campaign and encourage U.S. Latinos to give thanks for the healthy children in their lives and to help those who are not.
