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 will always be my boo

Alicia Keys
I don't know about y'all but I
know about us and uhh it's the only way we know how to rock (repeat)

Usher Verse
Do you remember girl, who was
he one who gave you your first kiss
Cause I remember girl who 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

Chorus:
Usher
It started when we were younger and you were mine (my boo)
Now another brothers' taken over but its'
still in your eyes (my boo)
Even though we use to argue it's alright
(it's alright girl, that's okay)
And if we haven't seen each other in a while,
but you will always be my boo

Alicia
Now if you loved when we were younger you were mine
And when I see from time to
time I still feel like, (that's my baby)
And if I see you no matter how I try to hide (I can't hide it)
And even though there's another man who's 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 younger and you were mine (my boo)
Now another brothers' taken over but its'
still in your eyes (my boo)
Even though we use to argue it's alright
(it's alright girl, that's okay)
And if we haven't seen each other in a while,
but you will always be my boo

Bridge
My ooh my ohh my ohh my ohh my boo (repeat)

Chorus:
Usher
It started when we were younger and you were mine (my boo)
Now another brothers' taken over but its'
still in your eyes (my boo)
Even though we use to argue it's alright
(it's alright girl, that's okay)
And if we haven't seen each other in a while,
but you will always be my boo

Alicia
I don't know about y'all but I know about us and uhh it's
the only way we know how to rock (repeat)
