Here's who's been announced to perform the national anthems before Spain faces Argentina.

Jennifer Hudson is performing the United States national anthem ahead of Spain vs. Argentina World Cup final.

The United States is not in the World Cup final, but its anthem will be performed, sparking one question: Why?

Also scheduled to appear during the opening ceremony are artists Katy Perry, Future, Anitta, LISA, Rema and Tyla. It is unknown if they will be performing or what role they will have in the show.
