[Usher & Alicia Keys]
There's always that one person that will always have your heart
You never see it coming 'cause you're blinded from the start
Knew that you're that one for me, it's clear for everyone to see
Ooh, baby, oh (yeah, uh, uh, uh)
(You gotta rock away to this one, come on)
You will always be my boo

See, I don't know 'bout y'all, but I know about us (oh!)
And, uh, it's the only way we know how to rock
I don't know 'bout y'all, but I know about us (oh!)
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 screaming your name
Girl, I was there and you were my baby

It started when we were younger, you were mine
My boo (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)
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 (my boo)
And I see it from time to time, I still feel like (I'm 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

[Alicia Keys & 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 screaming your name
I was there and you were my baby

It started when we were younger, you were mine
My boo (my boo)
Now another brother's taken over, but it's still in your eyes (yes, it is!)
My boo (my boo, my, oh)
Even though we used to argue, it's alright (it's alright, 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
My boo (you were my boo)
And I see it from time to time, I still feel like (I see it 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
(Though we haven't seen each other, you will always be my...)
You will always be my boo

Oh, my oh, my oh, my oh, my, my boo
My oh, my oh, my oh, my oh, my boo

It started when we were younger, 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 okay)
My boo
I know we haven't seen each other in a while
But you will always be my boo (play that back!)

[Usher]
I don't know 'bout y'all, but I know about us
And, uh, it's the only way we know how to rock
I don't know 'bout 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
