    Ms. "Frozen" was on fire at the Super Bowl.

    Idina Menzel belted out an outstanding live rendition of the national anthem ahead of the big game Sunday in Phoenix.

    Menzel was confident in all-black, singing what she assured would be live days before Super Bowl. After she sang the last note, she yelled in excitement: "Yes!"

    "I didn't want to rush," Menzel said in an interview after the performance. "I wanted to take in the moment and connect to the song that I was singing, not get swept away by all the grandiosity and excitement, and connect. And sing from my heart."

    The performance comes a month after the Tony-winning star was criticized for her performance of "Let It Go" during "Dick Clark's New Year's Rockin' Eve." At one point the crowd booed loudly, but it was because Patriots Coach Bill Belichick was shown on screen.

    Asked if the booing was a distraction, Menzel said: "I knew better. I knew I hit the note well, I wasn't worried it was me."

    "And they warn you," she added, laughing.

    John Legend, in typical form, brought the soul when he sang "America the Beautiful." He hit all the right notes while playing piano before the Seattle Seahawks take on the New England Patriots.

    Pop star Katy Perry will headline the halftime show. She will be joined by Missy Elliott and Lenny Kravitz.
