(Usher) 
(Dm7 Am7, Gm7, Am7) 
There's always that one person  
That will always have your heart 
You never see it coming 
'Cause you're blinded from the start 
Know that you the 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 cha'll 
But I know about us 
And uh..  
(Both) 
Is the only way we know who to rock... 
(Alicia) 
I don't know about cha'll 
But I know about us 
And uh ..  
(Both) 
Is the only way we know who to rock... 
(Usher) 
Do you remember girl 
I was the one who gave your first kiss 
'Cause I remember girl 
I was the one who said: "put you're lips like this" 
Even before all the fame and 
People screaming your name 
Girl I was there and you were baby 
 Chorus 
(Dm7 Gm7, A#7, Am7) 
(Usher) 
It started when we were younger 
You were mine, my boo 
Now another brother's taking over  
But it's still in your eyes, my boo  
Even though we used to argue, it's alright (It's alright girl, That's ok)  
I know we haven't seen each other in awhile 
But you wil always be my boo  
(Alicia) 
I was in love with you when we were younger 
You were mine, my boo 
And I see it from time to time 
I still feel like, my boo 
And I can see it no matter 
How I try to hide, my boo 
Even though there's another man who's in my life 
You will always be my boo 
(Alicia) 
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 
Chorus 
(Usher)
