Lyrics:

(Brandy)
Don't even think about callin' me crazy
You know you peeped that lady (yeah yeah)
And when I turned and look at you, you tried
To play it off but I can tell that you two were friends
She was just too nervous
She was lookin' like she was hurt
Like the memory had surfaced
It kinda got her pissed
I'm kinda wonderin' myself
And your really no help
Tell me how you two know each other so well
Cause I wanna know now
You better start talkin'

Who is she to you (yeah)
Don't lie to me
Who is she to you
My eyes can see
Something's going on between you two
I think you better let me know
That's fo sho

(Usher)
Who is she to me
Nobody babe
Who is she to me
No need to explain
I did nothing wrong, I swear to you
Nothing going on with us, that's what's up

See I don't know why homegirl keeps on eyen'
On everything, I'm not lyin' (oh no)
You make it worst actin' all insecure
She see you buggin'
So that's why she wanna be spotted(it ain't nothin' baby)
Go head and say you don't trust me
Always goin out of your way to bust me
You come up empty handed
I don't understand it
You better go head and listen
Girl you got it twisted
Don't be payin' that broad no attention
Cause you're the one i'm with
Don't be askin' me, yeah yeah, yeah

(Brandy)
Who is she to you
Don't lie to me
Who is she to you (who is she)
My eyes can see (my eyes)
Something's going on between you two
I think you better let me know
That's fo sho (yeah yeah)

(Usher)
Who is she to me
Nobody babe
Who is she to me
No need to explain
I did nothing wrong, I swear to you
Nothing going on with us, that's what's up

(Brandy)
Damn right I wanna know her name (why)
Tell me how you know her babe (I don't)
Why did she make that face (Ah no no)
You looked so ashamed

(Usher)
I'm not ashamed, I'm suprised
You think of me as that guy
Never done you wrong
What's going on.... I don't know

(Brandy)
Who is she to you (Who is she?)
Don't lie to me
Who is she to you (What did you do?)
My eyes can see
Something's going on between you two
I think you better let me know
That's fa sho

(Usher)
Who is she to me
Nobody Babe (Goin so crazy)
Who is she to me
No need to explain (To think that you were my baby)
I did nothing wrong I swear to you (Noo...No..Ahh)
Nothing going on with us, that's what's up

(Brandy)
Who is she to you (Baby)
Dont lie to me (Don't lie)
Who is she to you

Something's going on between you two (Aw yes it is yeah)
