The following are lyrics to the song Last Name. It was written by Carrie, Luke Laird, and Hillary Lindsey.
Last night I got served a little bit too much of that poison, baby
Last night I did things I'm not proud of, and I got a little crazy
Last night I met a guy, on the dance floor
And I let him call me baby
And I don't even know his last name
Oh, my mama would be so ashamed
It started off, Hey cutie where you from
And then it turned into, oh no what have I done
And I don't even know his last name (whoo)
We left the club right around three o' clock in the mornin'
His Pinto sittin' there, in the parkin' lot, well it should've been a warning
But I had no clue what I was gettin' into
So I blame it on the Cuervo (oh where did my manners go)
And I don't even know his last name
Oh, my mama would be so ashamed
It started off, Hey cutie where you from
And then it turned into, oh no what have I done
And I don't even know his last name (here we go)
Today I woke up, thinkin' 'bout Elvis, somewhere in Vegas
I'm not sure how I got here
Or how this ring on my left hand just appeared outta nowhere
I gotta go, I take the chips, and the Pinto and hit the road
They say what happens here, stays here, all of this'll disappear
There's just one little problem
I don't even know my last name
Oh, my mama would be so ashamed
It started off, Hey cutie where you from
And then it turned into, Oh no what have I done
And I don't even know my last name
What have I done, what have I done, what have I done
Oh, what have I done, I don't even know my last name, yeah, yeah
Mm, Yeah, yeah, yeah, yeah, aw
It started off, Hey cutie where you from
And then it turned into oh no what have I done
And I don't even know my last name
Oh, I don't even know my own last name
Yeah, yeah
