MINNEAPOLIS (CBS/AP) — Pop star Pink is battling the flu. But the 38-year-old singer is poised not to let that keep her from her dream of singing the National Anthem at the Super Bowl.

Pink, a native of Doylestown, Bucks County and Eagles fan is slated to sing the “The Star-Spangled Banner” on Sunday at the U.S. Bank Stadium before the Birds take on the New England Patriots in Super Bowl LII.

In a post on her Instagram, Pink said she is “trying to practice the flu away.”

Trying to practice the flu away. 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. 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! And here we are. I’ve arrived at another one of my dreams which is slowly becoming a sort of nightmare. 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. #spreadthelove #spreadthegerms #pleasegivememyvoiceback #ificansingimgonnakillit

This opportunity, she said, is one she’s been waiting for since she watched her idol, Whitney Houston, perform before the big game in 1991.

Pink powered through a pre-Super Bowl concert on Friday at Nomadic Live at the Armory in Minneapolis, still hitting high notes, flying in the air and dancing onstage. She even gave a shout-out to the City of Brotherly Love during the show.

She skipped some of the words during the songs, relying on her backup singers. But she was still energetic and spirited, ending the set with her signature high-flying athleticism while singing the pounding hit, “So What.”

The mother of two told the audience she had the flu and that her children “cough into my mouth and I can’t stop them ’cause they’re so cute.”

“I’m not going to sound like (crap) all night because you guys are going to help me,” she said. “We’re going to rock the (expletive) out and have a good time.”

As she began to sing “Beautiful Trauma” — from her recent album of the same name — she quickly stopped her band and told the crowd, “I can’t do it.”

“I hate this,” she said. “I can’t do that song. I’m sorry.”

She wore a loose white top, loose white pants and red heels as she ran up and down the stage, kicking off the show with the jam “Get the Party Started.” She later sang well-known hits like “U + Ur Hand,” ”Who Knew,” ”What About Us” and “Raise Your Glass.”

Despite feeling under the weather, she was exceptional when she covered 4 Non Blondes’ “What’s Up,” a crowd favorite.

“We’re gonna wake up the entire neighborhood,” she said before singing the song.
