Kristin Chenoweth may be Broadway royalty, but NBA fans were less than enchanted by her national anthem performance.

Ahead of a tense Game 7, Oklahoma City superfan Kristin Chenoweth had the honor of singing a thundering rendition of the national anthem.

The award-winning actress, singer, Oklahoma native, Oklahoma Hall of Fame inductee and unabashed Thunder fan sang “The Star-Spangled Banner” before Game 7 of the title series between the Thunder and the Indiana Pacers on Sunday night. Chenoweth’s performance aired live on ABC, shortly before tipoff of the season’s final game.
