Kelly Clarkson sang The National Anthem at Super Bowl XLVI and even critics were silenced by her fantastic rendition.

Kelly Clarkson, the very first winner of FOX's American Idol, was chosen to sing The National Anthem at Super Bowl 2012. Her performance came after numerous National Anthem flubs by the likes of Steven Tyler, Cyndi Lauper and Christina Aguilera (from last year's Super Bowl). Clarkson's one assignment was to cover The Star Spangled Banner without screwing it up.

And she far from screwed up. In fact, the 29-year-old passed with flying colors. She hit all the high notes with pitch-perfection and did not mess up one single lyric.

Twitter reactions to the performance lauded the singer for her poise and talent. Read some of the reactions to Kelly Clarkson's performance below:

After singing The National Anthem, Clarkson tweeted about jittery nerves. Guess what ....I've never been more nervous in my life than singing the national anthem at the Super Bowl tonight that was almost not fun I was so nervous! Fun night overall though! Thank you everybody for all of the nice things you're saying about my performance! I really appreciate it :) she wrote.

None of those nerves showed during the performance.

Before getting to Indianapolis, Clarkson was in a bit of a frenzy. She forgot her outfit for the night and had to have an assistant run back to Louisiana to get it.

Literally left my wardrobe at the hotel in Louisiana and my tour manager had to run back and get it. Now we're on the plane headed for the Super Bowl but that was a close one! I'm not sure if I could have pulled off spanx and heels while singing the anthem :) Clarkson tweeted before the show.
