[Intro: Katy Perry]
Yeah-yeah, yeah-yeah
Yeah-yeah, yeah-yeah

[Verse 1: Bonnie McKee]
Bad boy, bad boy, what you gonna do? 
Caught you double-dipping
Baby, now you see 'em too
Bad boy, bad boy, what you got to say? 
Suddenly, you're stuttering
Like you forgot my name
Bad boy, bad boy, should've cover up your tracks
'Cause both of us are on to you
And now the case is cracked
Hey boy, enjoy, beggin' on the phone
'Cause, boy, you made your bed
Now you can sleep in it alone

[Pre-Chorus: Bonnie McKee]
Who do you think you are?
You belong behind cold bars
Creeping like a criminal
But we are here to let you know

[Chorus: Katy Perry]
You're not above thе laws of love (Yeah-yeah, yеah-yeah)
You can't abuse it like a drug (Yeah-yeah, yeah-yeah)
She said you told her all the same things
She said you called her all the same names
[Post-Chorus: Bonnie McKee &(Katy Perry)]
Bad boy, bad boy, what you gonna do?
What you gonna do?
(Yeah-yeah, yeah-yeah)
(Yeah-yeah, yeah-yeah)

[Verse 2: Bonnie McKee]
Bad boy, bad boy, you thought you were so good 
You swore I was the one
I guess that I'm misunderstood
Bad boy, bad boy, you sick son of a gun
Always into trouble
Always leaving on the run

[Pre-Chorus: Bonnie McKee]
Who do you think you are?
You belong behind cold bars
Creeping like a criminal
But we are here to let you know

[Chorus: Katy Perry]
You're not above the laws of love (Yeah-yeah, yeah-yeah)
You can't abuse it like a drug (Yeah-yeah, yeah-yeah)
She said you told her all the same things
She said you called her all the same names
[Post-Chorus: Bonnie McKee & (Katy Perry)]
Bad boy, bad boy, what you gonna do?
What you gonna do?
(Yeah-yeah, yeah-yeah)

[Bridge: Bonnie McKee & (Katy Perry)]
Who do you think you are?
(Yeah-yeah, yeah-yeah)
You belong behind cold bars
(Yeah-yeah, yeah-yeah)
Creeping like a criminal
(Yeah-yeah, yeah-yeah)
We are here to let you know
Bad boy, bad boy, what you gonna do?
Bad boy, bad boy, what you got to say?

[Chorus: Katy Perry]
You're not above the laws of love (Yeah-yeah, yeah-yeah)
You can't abuse it like a drug (Yeah-yeah, yeah-yeah)
She said you told her all the same things
She said you called her all the same names

[Post-Chorus: Bonnie McKee & (Katy Perry)]
Bad boy, bad boy, what you gonna do?
What you gonna do?
(Yeah-yeah, yeah-yeah)
(Yeah-yeah, yeah-yeah)
