Lyrics:

[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
Ooh baby ooh you'll always be my boo

[Alicia Keys]
I don't know 'bout y'all
But I know about us and uh
This is the only way
We know how to rock

I don't know 'bout y'all
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

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
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
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

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

[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
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
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

[Usher]
My oh, my oh, my oh, my oh, my boo

[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 taking over
But it's still in your eyes my boo
Even though we used to argue it's alright
I know we haven't seen each other
In a while but you will always be my boo

[Both]
I don't know 'bout y'all
But I know about us and uh
This is the only way
We know how to rock

I don't know 'bout y'all
But I know about us and uh
This is the only way
We know how to rock
