[Intro: CeeLo Green]
Come on, let's do it
Ah, do it, ah
Do it like a 9 to 5
I said do it
Ah, do it, ah
Do it till you're good 'n tired
Hey hey

[Verse 1: Christina Aguilera]
I was sitting all alone, yeah
A lot on my mind
Felt a tap on my shoulder
Out goes my eyes
I wasn’t in the mood for another man
Telling me lies
How can a girl say no when you flash that sexy smile
And you say

[Pre-Chorus: CeeLo Green & (Christina Aguilera)]
Aah-ahh, ey ey (Eeey)
Wanna see you get nasty (Hit me)
Wanna see you shake yo ass, babe (Yeah)
Hey hey

[Chorus: Christina Aguilera]
N-A-S-T-Y, you're nasty
But baby, I don't mind
Love the way you're talking nasty
You know you're just my type (Boy, you're just so nasty)
N-A-S-T-Y, you're nasty
Baby, I don't mind
Love the way you're talking nasty
You know you're just my type
[Verse 2: Christina Aguilera]
In the middle of the floor now
I just don’t care
See my body so low now
Crowd stops instead
Let them say what they want, but I'm feeling' it
And it’s for you, baby
Tell me how can a girl say no when you're calling out my name
And you say

[Pre-Chorus: CeeLo Green & (Christina Aguilera)]
Aah-ahh, ey ey (Eeey)
Wanna see you get nasty (Hit me)
Wanna see you shake yo ass babe (Yeah)
Hey hey

[Chorus: Christina Aguilera]
N-A-S-T-Y, you're nasty
But baby, I don't mind
Love the way you're talking nasty
You know you just my type (Boy you're just so nasty)
N-A-S-T-Y, you're nasty
Baby, I don't mind
Love the way you're talking nasty
You know you're just my type
[Bridge: Christina Aguilera]
What's your fantasy? (Ooh, nasty nasty)
Tell them all to me (Ooh, nasty nasty)
Don’t you be afraid (Ooh, nasty nasty)
Share your nasty secret, baby, hey

[Pre-Chorus: CeeLo Green & (Christina Aguilera)]
Aah-ahh, ey ey (Eeey)
Wanna see you get nasty (Hit me)
Wanna see you shake yo ass, babe (yeah)
Hey hey

[Chorus: Christina Aguilera]
N-A-S-T-Y you’re nasty
Boy you're just so nasty
N-A-S-T-Y, you're nasty
But baby, I don't mind
Love the way you're talking nasty
You know you just my type (Boy, you're just so nasty)
N-A-S-T-Y, you're nasty
Baby, I don't mind, yeah
I love the way you're talking nasty
Boy, you're just so (Nasty)
Hey
