Pink spit out her throat lozenge on the field before singing the national anthem at the Super Bowl

Despite battling the flu, Pink delivered a powerful rendition of the national anthem to kick off Super Bowl LII on Sunday night in Minneapolis.

The Grammy-winning singer had revealed on social media earlier in the weekend that she was "trying to practice the flu away" ahead of her big moment and, though the strain in her voice was audible, she was still able to put her powerhouse vocals on full display.

For her performance, the singer opted for a gray-and-white camo blouse over white silk pants. To help her brave the cold, she also wore a silver silk bomber jacket with shoulder pads.

Also on-hand were husband Carey Hart and daughter Willow Sage.

What may overshadow her performance, though, is what she did just seconds before the music started playing at U.S. Bank Stadium: She spit out a throat lozenge onto the field.

The moment quickly went viral on Twitter, with people loving the "hard as hell" moment, but also wondered if someone was going to pick it up before the game started so that it didn't get stuck in the players' cleats.

Regardless, Pink clearly wasn't going to let the flu take too much away from singing the national anthem in front of 100 million people tuning into the Super Bowl -- the most-watched telecast every year -- which is essentially the highest-pressure gig in music.

On Saturday, Pink opened up about how much the opportunity meant to her, calling out Whitney Houston's iconic rendition of the song from 1991 as a constant moment of inspiration for her.

"I’ve 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," she wrote. "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!"

"I’ve arrived at another one of my dreams which is slowly becoming a sort of nightmare," she continued. "I will tell you, this is one of the biggest honors of my life, singing this song in front of my family, my military family, my dad and brother and step mama and family and the world. And the EAGLES!?!?! I promise I will do my best, as I always do. As far as the gremlins that got me into this mess, you can cough at me for the rest of your lives. If it’s a contest, babies, you win."

Bravo, Pink!

UPDATE: Pink took to Twitter during the game on Sunday night to end the speculation around the moment.

"It was a throat lozenge," she said.

An earlier version of this article stated that the singer had gum in her mouth, and we've updated the copy to reflect that it was indeed a throat lozenge.
