Let us bow down to the powerhouse that is Idina Menzel.

After shaking off criticism from her New Year's Eve performance of 'Let It Go' (during which she hit a rather sour note), the 'Frozen' actress proved to the world why she's a musical superstar as she belted out the National Anthem at the 2015 Super Bowl.

The Broadway star belted the patriotic tune with ease, gorgeously elongating each note as the crowd cheered wildly. Though the pressure was on -- just ask Katy Perry: Performing in front of a stadium-sized crowd, as well as more than a million people watching at home, is no easy task -- Menzel was unflappable, proudly performing the Americana song with incredible finesse and skill. And take it from someone who has seen Idina Menzel perform multiple times in Broadway's 'Wicked': Girl can sing live.

Check out Idina Menzel's performance of the National Anthem in the video above.
