(Usher:)
There´s always that one person
That will always have your heart
You´ll never see it coming
Cause you´re blinded from the start
Know that you´re that one for me
It´s clear for everyone to see
Oh baby oh you´ll always be my boo

(Alicia:)
I don´t know about you´ll
But I know about us and ouh
This is the only way
We know how to rock
I don´t know bout you´ll
But I know about us and uh
This is the only way
We know how to rock

(Usher:)
Do you remember girl
I was the one who gave you your first kiss
Cause I remember girl
I was the one who said put your lips like this
Even before all the fame and
People screaming your name
Girl I was there when you were my baby

{Refrain:} (Usher:)
It started when we were younger
You were mine (my boo)
Now another brother´s taken over
But it´s still in your eyes (my boo)
Even though we used to argue
It´s alright (my boo)
I know we haven´t seen
Each other in a while
But you will always be my boo

(Alicia:)
I was in love with you
When we were younger
You were mine (my boo)
When I see you from time to time
I still feel light (my boo)
No matter how I try to hide
Even though there´s another man who´s in my life
You will always be my boo

Yes I remember boy
´Cause after we kissed
I could only think about your lips
Yes, I remember boy
The moment I knew
You were the one I could
Spend my life with
Even before all the fame
And people screaming your name
I was there and you were my baby

{au Refrain}

(Alicia:)
I was in love with you
When we were younger
You were mine (my boo)
When I see you from time to time
I still feel light (my boo)
No matter how I try to hide
Even though there´s another man who´s in my life
You will always be my boo

(Usher:)
My ooh, my ooh, my ooh, my ooh, my boo

(Alicia:)
My ooh, my ooh, my ooh, my ooh, my boo

{au Refrain}

(Alicia & Usher:)
I don´t about you´ll
But I know about us and uh
It´s the only way we know how to rock
I don´t about you´ll
But I know about us and uh
It´s the only way we know how to rock
