The singer gave a soulful rendition of the National Anthem, hitting every note and remembering every word despite being “really nervous” prior to her all-star performance.

“Just finished rehearsing the anthem in Indy … wow, I’m actually really nervous about singing at the Super Bowl ha!” she wrote on her WhoSay account. “Here’s hoping I nail it and don’t screw it up!

The two-time Grammy winner, donning a fitted black dress, tackled the song after Blake Shelton and Miranda Lambert’s performance of “America the Beautiful.”

After the game, the Texas native checked in with fans again, writing, “Guess what ….I’ve never been more nervous in my life than singing the national anthem at the Super Bowl tonight ….wow 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

Lyric “Mr. Know It All” :

Mr. Know It All
Well ya think you know it all
But ya don’t know a thing at all
Ain’t it, ain’t it something y’all
When somebody tells you something ’bout you
Think that they know you more than you do
So you take it down another pill to swallow

Mr. Bring Me Down
Well ya, ya like to bring me down, don’t you?
But I ain’t laying down, baby, I ain’t goin’ down
Can’t nobody tell me how it’s gonna be
Nobody’s gonna make a fool out of me
Baby, you should know that I lead not follow

[Chorus:]
Oh you think that you know me, know me
That’s why I’m leaving you lonely, lonely
‘Cause baby you don’t know a thing about me
You don’t know a thing about me
You ain’t got the right to tell me
When and where to go, no right to tell me
Acting like you own me lately
Yeah baby you don’t know a thing about me
You don’t know a thing about me

Mr. Play Your Games
Only got yourself to blame when you want me back again
But I ain’t falling back again
‘Cause I’m living my truth without your lies
Let’s be clear baby this is goodbye
I ain’t coming back tomorrow

[Chorus:]
Oh you think that you know me, know me
That’s why I’m leaving you lonely, lonely
‘Cause baby you don’t know a thing about me
You don’t know a thing about me
You ain’t got the right to tell me
When and where to go, no right to tell me
Acting like you own me lately
Yeah baby you don’t know a thing about me
You don’t know a thing about me

[Bridge:]
So what you’ve got the world at your feet
And you know everything about everything
But you don’t
You still think I’m coming back but baby you’ll see yeah…

[Chorus:]
Oh you think that you know me, know me
That’s why I’m leaving you lonely, lonely
‘Cause baby you don’t know a thing about me
You don’t know a thing about me
You ain’t got the right to tell me
When and where to go, no right to tell me
Acting like you own me lately
Yeah baby you don’t know a thing about me
You don’t know a thing about me

Mr. Know It All
Well ya think you know it all
But ya don’t know a thing at all
Yeah baby you don’t know a thing about me
You don’t know a thing about me

“I’m from a small town, so everyone’s married with children or about to have children. It’s a little hard when you go home and people are like — and that’s why people think I’m gay — because they’re like, ‘Why aren’t you married?’ And I’m like, ‘It doesn’t happen for everyone right off the bat!’”

Kelly Clarkson has blasted her record label bosses for choosing to release Already Gone as her next single – because it sounds too similar to Beyonce Knowles’ hit tune Halo.

The American Idol winner has been forced to defend the track after receiving criticism for its likeness to Beyonce’s recent release, but Clarkson insists any comparisons are down to songwriter and OneRepublic frontman Ryan Tedder, who worked with both artists on their respective songs.

Kelly Clarkson, currently at the top of the U.S. pop charts, said on Tuesday she was not a lesbian but sometimes wished she was because “often times men are very hard for me.”

“I could never be a lesbian. I would never want to date (someone like) myself, ever. I’m a crazy person. I need some kind of stable, quiet man,” Clarkson, 26, said.
