There's always that one person that will always have your heart
You'll never see [bad word] cause you're blinded from the start
Know that you're that one for me, it's clear for everyone to see
Ooh baby aw..
You'll always be my boo

[Alicia Keys]
See, 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

[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 and you were my baby

It started when we were younger you were mine (my boo)
Now another brother's taken over but it's still in you're eyes (my boo)
Even though we use to argue it's all right (my boo)
I know we haven't seen each other in a while
But you will always be my boo

[Alicia Keys]
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 like (my boo)
You can see it no matter how I try to hide (my boo)
And 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 can only think about you're 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

[Usher]
It started when we were younger you were mine (my boo)
Now another brother's taken over but it's still in you're eyes (my boo)
Even though we use to argue it's all right (my boo)
I know we haven't seen each other in a while
But you will always be my boo

[Alicia Keys]
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 like (my boo)
You can see it no matter how I try to hide (my boo)
And even though there's another man who's in my life
(What we have is in each other)
You will always be my... boo

[Usher]
My oh my oh my oh my oh my my boo...

[Usher and Alicia Keys]
My oh my oh... my oh my oh my boo...

[Usher]
It started when we were younger you were mine (my boo)
Now another brother's taken over but it's still in you're eyes (my boo)
Even though we use to argue it's all right (my boo)
I know we haven't seen each other in a while
But you will always be my boo
(Uh uh)

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
