National Anthem singer prepares for Packers playoff game by singing in walk-in freezer

MILWAUKEE (CBS 58) -- Surrounded by frozen food, Grace Weber practiced singing the national anthem for Saturday's game at Lambeau Field. 

Saturday's playoff game again against the 49ers is expected to be below zero. 

Weber, who is from Milwaukee, is currently in Los Angeles, and she said in an Instagram post that she isn't prepared to sing in them. 

"The weather is going to be -5 on Saturday, and I'm going to be singing on Lambeau Field; and I realized I really don't know what it's like to sing in freezing temperatures," said Weber. 

So Weber got creative by finding a walk-in freezer to practice in! 

With just a hat and a light jacket, she didn't miss a note as she belted the Star-Spangled Banner. She may need some gloves once she gets to the Frozen Tundra.
