[Usher:]
There's always that one person
That will always have your heart
You 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
You gotta rock your way with this one
Ooh you will always be my boo
Come on

[Alicia:]
I don't know bout you all
But I know about us and uh
It's the only way
We know how to rock
I don't know bout you 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 screaming your name
Girl I was there when 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 your eyes my boo
Even though we used to argue it's alright
It's alright girl my boo that's OK
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
When I see you 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

[Alicia:]
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 taken over
But it's still in your eyes my boo
Even though we used to argue it's alright
It's alright my boo it's OK
I know we haven't seen each other
In awhile but you will always be my boo

[Alicia:]
