Another really simple one from Britney's 'Femme Fatale' album...
This is the same key as the recording.  Same kind of chord sequence repeated throughout

VERSE 1 + CHORUS

Am  Em  D   Am

He is a hustler 
He's no good at all 
He is a loser, he's a bum
He lies, he fluffs he's unreliable 
He is a sucker with a gun
I know you told me I should stay away 
I know you said he's just a dog astray 
He is a badboy with a tainted heart
And even I know this ain't smart

But mama, I'm in love with a criminal 
And this type of love isn't rational, it's physical
Mama, please don't cry, I will be alright
All reason aside, I just can't deny
I love the guy

VERSE 2 + CHORUS

Am  Em  D  Am

He is a villain by the devil's law
He is a killer just for fun
That man's a snitch and unpredictable
He's got no conscience, he got none
All I know
Shoulda let go, but no
Cause he's a badboy with a tainted heart 
And even I know this ain't smart 

But mama, I'm in love with a criminal 
And this type of love isn't rational, it's physical
Mama, please don't cry, I will be alright
All reason aside, I just can't deny
I love the guy

MID 8

F              Am   G           Am
And he's got my name tatooed on his arm
His lucky charm
F                     Am
So I guess it's okay,
             G
He's with me
F                   Am           G
And I hear people talk (People talk)
              Am
Trying to make remarks, keep us apart
F                     Am
But I don't even hear
        G
I don't care

REPEAT CHORUS
