[Verse 1: Ester Dean]
Oh, I guess I'm a bad, bad man, yeah
And I ain't no good for you
Tell me where you'll find a better man, yeah
Who's gonna treat you better than I do?

[Pre-Chorus: Chris Brown]
'Cause I ain't trickin' in the club
I givin' him no love
All them thotties tryna fuck with me
I ain't trickin' for nobody else
Askin' you, nobody else
Girl, it's all in your head

[Chorus: Ester Dean]
It's all in your head, oh, girl
It's all in your head, oh, girl
And every time I go out
You claim I'm with every girl
And lookin' at every girl
Think I'm smashin' every girl
Can't be fuckin' every girl, oh
It's all in your head

[Verse 2: Chris Brown]
If I gotta be the bad man
Then at least you gotta tell me why
Girl, what the hell is up with this?
You checkin' through my phone and shit
Oh, no, hell no
[Pre-Chorus: Chris Brown]
I ain't trickin' in the club
I givin' him no love
All them thotties tryna fuck with me
I ain't trickin' for nobody else
Askin' you, nobody else
Girl, it's all in your head

[Chorus: Ester Dean, Chris Brown]
It's all in your head, oh, girl (Oh, girl)
It's all in your head (Your head), oh, girl (Oh, na-na-na, na-na-na-na)
And every time I go out
You claim I'm with every girl
And lookin' at every girl (Hey)
Think I'm smashin' every girl (Oh, girl)
Can't be fuckin' every girl, oh
It's all in your head (Head)

[Bridge: Chris Brown]
It's all in your brain
Brain, brain, brain, brain, your head
It's all in your brain
Brain, brain, brain, brain, your head
It's all in your brain
Brain, brain, brain, brain, your head
[Chorus: Ester Dean, Chris Brown]
It's all in your head, oh, girl (Oh, woah)
It's all in your head (It's all in your head, all in your head), oh, girl
And every time I go out (Oh)
You claim I'm with every girl
And lookin' at every girl (Babe)
Think I'm smashin' every girl
Can't be fuckin' every girl, oh (Oh)
It's all in your head (Woah-woah, oh)
It's all in your head, oh, girl (In your head, girl, in your head, girl, yeah)
It's all in your head, oh, girl
And every time I go out
You claim I'm with every girl
And lookin' at every girl
Think I'm smashin' every girl
Can't be fuckin' every girl, oh
It's all in your head
