Super Bowl: Pink Battles Flu to Sing National Anthem

Right before the performance, the singer-songwriter spit out a throat lozenge.

Pink delivered a powerful rendition of the National Anthem to open Super Bowl LII on Sunday, even as she battled the flu.

It was the artist's first time performing at the ultimate football event in American culture, putting her on a list of performers including Luke Bryan, Idina Menzel, Lady Gaga, Alicia Keys, Kelly Clarkson, Carrie Underwood and Billy Joel.

Right before the performance, the singer-songwriter spit out a throat lozenge, prompting some amused tweets from viewers who assumed it was gum. She later tweeted a clarification. During her performance, a few performers were shown with tears in their eyes and after, a small number of fighter jets flew over the U.S. Bank Stadium in Minneapolis.

A few days earlier, on Friday, the artist revealed at a sold-out concert at Minneapolis' The Armory that she had come down with the flu. Though she worked through her set with songs like "Get the Party Started," "U + Ur Hand" and "What About Us," she stopped at singing "Beautiful Trauma." "I can't do that song, I'm sorry," she said.

Pink proved determined to perform at the Super Boel in spite of her illness, however. In an Instagram post on Friday, she posted an image of herself practicing in the stadium. "Ive been waiting to sing this song since 1991 when I saw my idol, Whitney Houston, own this song. And now, my chance has finally come. And it just so happens that this chance comes when I have two small Petri dish kids who literally cough INTO MY MOUTH and rub their snot on my cheek. You can’t write this stuff I swear!" she wrote.

No players appeared to be kneeling during the National Anthem. At the Television Critics Association's press tour in January, NBC Sports executive producer Fred Gaudelli promised that NBC would show any players taking a knee in protest of police brutality against black Americans if it happened during the Sunday's game. "When you're covering a live event, you're covering what's happening. If there are players who chose to kneel, they will be shown live," he said.
