歌手：Justin Bieber&Ludacris歌词：You know you love me,I know you careYou shout whenever, And I'll be thereYou want my love, You want my heartAnd we will never ever ever be apart
Are we an item? Girl quit playingWere just friends, Or are we sayingSo theres another one, Looks right in my eyes
My first love broke my heart for the first time,And I was likeBaby, baby, baby noooMy baby, baby, baby nooMy baby, baby, baby noooI thought youd always be mine mine
Baby, baby, baby noooMy baby, baby, baby nooMy baby, baby, baby noooI thought youd always be mine, oh oh
For you, I would have done whateverAnother chance and we, We get togetherAnd wanna play it cool, About loosin' youI'll buy you anything, I'll buy you any ringAnd i'm in piece , baby fix meAnd you'll shake me til' you wake me from this bad dreamIm going down, down, dooownAnd just can't believe my first love won't be around 
Baby, baby, baby noooBaby, baby, baby noooMy baby, baby, baby nooMy baby, baby, baby noooI thought youd always be mine
When i was 13 i had my first loveHere was nobody to compare my baby And nobody came between us or could ever come aboveShe had me goin crazy Oh i was starstruck.She woke me up daily dont need no starbucksShe made my heart poundAsking for a beat when i see her in the street And in the school on the playgroundBut i really wanna see her on the weekendsShe knows she got me dazy Cause she was so amazing and now my heart is breaking But i just keep on sayinBaby, baby, baby noooMy baby, baby, baby nooMy baby, baby, baby noooI thought youd always be mine  x2
Now Im all gone
