Carrie Underwood is a national treasure!

The 35-year-old singer hit the rink on Sunday to perform the "Star-Spangled Banner" ahead of the Nashville Predators taking on the Winnipeg Jets during the 2018 NHL Stanley Cup Playoffs at Bridgestone Arena in Nashville, Tennessee.

"She’s a beloved music superstar, but today she’s a proud hockey fan and a number one Preds fan. Please welcome, Carrie Underwood," the announcer said upon introducing the country crooner. 

Underwood stayed for the game, cheering on her husband from her box seats, but the home team still lost to the Jets, 5 to 4.

Also over the weekend, the "Cry Pretty" singer shared a close-up video of her face to her Instagram Story as she joked about her husband's "annoying" habit in the car. In Saturday's video, Underwood softly said "help me" as she panned the camera over to Fisher, who was making a squeaking noise into his hands while driving. "Must we? So annoying," she captioned the funny clip. 

Underwood, who broke her wrist and had to get 40 to 50 stitches on her face after falling at her Nashville, Tennessee, home last November -- has been open with fans about her struggles to accept looking "a bit different."
