There's always that one person
That will always have your heart
You never see [bad word] ‘cause you're blinded from the start
I know that you're that one for me
It's clear for everyone to see
Oooh baby, you will always be my boo

[Alicia Keys]
I don't about yall
But I know about us and uh 
It's the only way we know how to rock
I don't about yall
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
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 your eyes (my boo)
Even though we used to argue
It's alright (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 light (my boo)
No matter how I try to hide
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 taken over
But it's still in your eyes (my boo)
Even though we used to argue

Each other in a while
But you will always be my boo

No matter how I try to hide

You will always be my boo

My all, my all, my all, my all, my boo
My all, my all, my all, my all, my boo

It's the only way we know how to rock
