[Verse 1: Chris Brown]
I'm not your enemy, but you keep pressin' me
So I'ma have to give you what you want, want right now
And we ain't ever been friends, but the thing between me and your man
We gon' keep between us, uh-huh
Don't act like you already know
You comin' home late, you stayin' all night with me
You should say "bye-bye" tonight
'Cause this gon' be your last time tonight, oh-oh

[Pre-Chorus: Keri Hilson]
I see you lookin' like you wanna say somethin', say somethin'
Mouth open but you don't say nothin', no
'Cause you be with her puttin', puttin' on, frontin' like you ain't did nothin'
You don't want her, you should let her go
'Cause you got some nerve bringin' her around me
Gotta keep my cool so nobody will see
If she knew what you was doin' like I know, then that'd make her crazy
Is that really what you wantin', baby?

[Chorus: Chris Brown, Chris Brown & Keri Hilson]
If your girl only knew (Ayy), knew, k-k-k-k-knew (Knew)
That you been dealin' with me (Me)
And you been trickin' on me (Me)
When you was lonely (Yeah, knew, knew)
If your girl only knew (Ayy), knew, k-k-k-k-knew (Knew)
In your business 'cause I'm spendin' my time with your guy
And it don't matter if it's wrong or right, oh-woah
[Verse 2: Chris Brown, Keri Hilson]
I'm not your enemy, but you keep pressin' me
So I'ma have to give you what you want, want right now
And if anything, you should really be talkin' to your man before he's long gone
But he's already gone, my picture in his phone
Textin' me with all them X and O's
You should say "bye-bye" tonight
It's gon' be your last time tonight, oh-oh

[Pre-Chorus: Keri Hilson]
I see you lookin' like you wanna say somethin', say somethin'
Mouth open but you don't say nothin', no
'Cause you be with her puttin', puttin' on, frontin' like you ain't did nothin'
You don't want her, you should let her go
'Cause you got some nerve bringin' her around me
Gotta keep my cool so nobody will see
If she knew what you was doin' like I know, then that'd make her crazy
Is that really what you wantin', baby?

[Chorus: Chris Brown, Chris Brown & Keri Hilson]
If your girl only knew (Ayy), knew, k-k-k-k-knew (Knew)
That you been dealin' with me (Me)
And you been trickin' on me (Me)
When you was lonely (Yeah, knew, knew)
If your girl only knew (Ayy), knew, k-k-k-k-knew (Knew)
In your business 'cause I'm spendin' my time with your guy
And it don't matter if it's wrong or right, oh-woah
