Alicia Keys)    [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:]    It's like 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
