[Intro: Usher, Alicia Keys & Both]
There's always that one person that will always have your heart
You'll never see it comin' 'cause you're blinded from the start
Know that you're that one for me, it's clear for everyone to see
Ooh baby, ooh, yeah (You gotta rock away to this one)
You will always be my boo (Come on)
See, I don't know 'bout y'all, but I know about us and, uh (Oh!)
It's the only way we know how to rock
I don't know 'bout y'all, but I know about us and, uh (Oh!)
It's the only way we know how to rock

[Verse 1: 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 screamin' your name
Girl, I was there when you were my baby

[Chorus: Usher & Alicia Keys]
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 (It's alright, girl, that's okay)
I know we haven't seen each other in a while
But you will always be my boo
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, that's my baby)
And I can see it no matter how I try to hide (I can't hide it, my boo)
And even though there's another man who's in my life
You will always be my boo
[Verse 2: Alicia Keys with Usher]
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 screamin' your name
I was there
And you were my baby

[Chorus: Usher, Alicia Keys & Both]
It started when we were younger, you were mine (You were mine; My boo)
Now, another brother's taken over, but it's still in your eyes (Yes, in here; My boo)
Even though we used to argue, it's alright (It's alright now, it's okay; My boo)
I know we haven't seen each other in a while
But you will always be my boo
I was in love with you when we were younger, you were mine (You were mine, my boo; My boo)
And I see it from time to time, I still feel like (It's still in your eyes; My boo)
And I can see it no matter how I try to hide (It's alright now, it's okay; My boo)
And even though there's another man who's in my life (But we hadn't seen each other)
You will always be my boo (You will always be my...)

[Bridge: Usher, Alicia Keys & Both]
Oh, my oh, my oh, my oh, my, my boo
My oh, my oh, my oh, my oh, my boo

[Chorus: Usher, Alicia Keys & Both]
It started when we were younger, you were mine (You were mine; My boo)
Now another brother's taken over, but it's still in your eyes (You were mine) (My boo)
Even though we used to argue, it's alright (It's alright, it's alright, it's okay, it's okay) (My boo)
I know we haven't seen each other in a while (In a while)
But you will always be my boo
[Outro: Usher]
I don't know about y'all, but I know about us and, uh
It's the only way we know how to rock
I don't know about y'all, but I know about us and, uh
It's the only way we know how to rock
It started when we were younger
My boo
'Nother brother's taken over
Just stand
