[Hook: Trey Songz]
Girl I want you to know (whoo)
I can´t get you out of my head
My head my head (naawww)

Girl I want you to know
I don´t even know what you did
You did you did
But I love it

[Verse 1: Lupe Fiasco]
Uh Uh
Everything hooks
Everything works, you´re a real good cause
I´m a real good verse, freestyle unrehearsed
So clean no curse
And when the song´s gone man everything hurts
So I put it in reverse
Go back to the scene where I seen you first
Yeah, I need you to sing that single again
Play that video I seen you up in
A hundred million scenes in my mind all day
Call in and request on the line always
Yeah, the president of your fan club
Leave them players all behind like a bad love

[Hook: Trey Songz]
Girl I want you to know
I can´t get you out of my head
My head my head (I can´t get you out now)

Girl I want you to know
I don´t even know what you did
You did you did
But I love it (Wait)

[Verse 2: Lupe Fiasco]
Playa need a minute
Like a time out in tennis ´for I finish
How´d I get in this
Maybe ´was your hair, maybe ´was your flair
Maybe it´s the heels and the way you wear
Maybe it´s your real and the way you care
You don´t care if I´m ill or a millionaire
The only thing that matters that the feeling´s there
Your smile is so bright it´s like a grills in there
High off life, don´t need a pill in there (nah)
You´re killing me, I think I need a will in here
Got me feeling real skills impaired
Hard to describe why you´re still in here

[Hook: Trey Songz]
Girl I want you to know
I can´t get you out of my head
My head my head

Girl I want you to know
I don´t even know what you did
You did you did
But I love it (but I love it)

[Bridge: Trey Songz & Lupe Fiasco]
Don´t care what nobody say
Cause I like it girl
Might go crazy try´na figure this out love (but I like it girl)
Don´t even know why I feel this way
Cause I like it girl
Caught up in something that I can´t get out of (but we like it girl)

[Hook: Trey Songz]
Girl I want you to know
I can´t get you out of my head (I can´t get you out now)
My head my head (said I can´t get you out now)

Girl I want you to know
I don´t even know what you did
You did you did (you did you did you did)
But I love it

Girl I want you to know (I want you to know)
I can´t get you out of my head (lupe)
My head my head (trey)
I want you to know (yeah)

Girl I want you to know (oh oh oh)
I don´t even know what you did (just making sure)
You did you did (i don´t even know)
But I love it
