On Monday night (April 17), Carrie Underwood surprised a packed Bridgestone Arena with an electrifying performance of the National Anthem before the Nashville Predators hosted the Chicago Blackhawks in the Pred's first round Stanley Cup playoff.

"Please rise and welcome seven-time Grammy winner and longtime Nashville Predators fan Carrie Underwood," the game's announcer said before cameras panned to Underwood on the ice. The crowd erupted in thunderous applause before she even hit the high note leading up to "in the land of the free."

Nashville Mayor Megan Barry then joined Underwood on the ice to start the game with a Predators towel twirl.

The game ended a little after midnight with the Predators defeating the Blackhawks in overtime 3-2 for a 3-0 lead in the Western Conference quarterfinals.

For the game, Underwood wore a No. 12 jersey in support of her husband and Preds captain Mike Fisher with a custom blue and gold manicure by Parlor 3 esthetician Jennifer Tsourvakas.
