[Usher intro]
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 intro]
I don't know bout cha'll
But I know about us and uh
This is the only way
We know how to rock
I don't know bout cha'll
But I know about us and uh
This is the only way
We know how to rock

[Usher Verse]
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

[Chorus]
[Usher]
It started when we were young girl
You were mine my boo
Now another brother's taking over
But its still in your eyes my boo
Even though we used to argue it's alright
I know we haven't seen each other
In awhile but you will 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 in my life
You will always be my boo

[Alicia Verse]
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]
It started when we were young girl
You were mine my boo
Now another brother's taking over
But its still in your eyes my boo
Even though we used to argue it's alright
I know we haven't seen each other
In awhile but you will 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 in my life
You will always be my boo

[Usher]
My oh, My oh, My oh, My oh, My Boo

[Alicia]
My oh, My oh, My oh, My oh, My Boo

[Chorus]
[Usher]
It started when we were young girl
You were mine my boo
Now another brother's taking over
But its still in your eyes my boo
Even though we used to argue it's alright
I know we haven't seen each other
In awhile but you will always be my boo

[Alicia & Usher]

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