The Super Bowl 54 national anthem singer has a longer history than most performing "The Star-Spangled Banner" at major sporting events.
Sunday's event at Hard Rock Stadium in Miami will mark the fifth time Demi Lovato sings the national anthem in front of a major television audience.
The pop artist has opened a pair of World Series contests, one NFL matchup and the fight between Floyd Mayweather Jr. and Conor McGregor in 2017.
With kickoff slated for 6:30 p.m. ET, Lovato should take the field for the anthem a few minutes prior during what is typically an extended on-field pregame ceremony.
