《Baby》的歌詞中有小賈斯汀的演唱，以下是小Baby部分的部分歌詞：
Verse 1:
Yo check it out
Yo I don't know what they're saying
But I like the way it sounds
Just got a feeling all the chicks are listening
My world's getting heavier on me
(But it's all good) I got the G5 and we can get it lifted
Chorus:
Baby baby, when we on the ground
Under the lights and we walking around
Gonna gonna, it don't matter, my love for you is incurable
Can't nobody, take us anywhere, cause we all on the same thing
Verse 2:
All my life, I've been waiting for someone like you
Take you for what you want, yeah
Your so right here in front of me and you ain't gotta ask why
(What I like) when we fall in love with all our dreams in our minds
Bridge:
Girl I gotta tell you I love you, when we first met you
It was in my heart, my dear it was from the start, you are everything my world's spinning around (my world's spinning)
You my Valentine, we never ending everynight I say my prayers laying next to you, holding your hand under my head baby so tired but yeah your love just puts a smile in my head when you walk through the door its all so true what your doin for me is pure cocaine its your thrill , its your spice , its your cherry pie , i ain't ever gonna deny , its a fine line , and your in it , your the only one that i want to win , no one else , and i'm down , down , down , down , i'm down , i'm down , down , down , yeah , yeah , yeah , yeah , yeah , yeah
Chorus:
Baby baby, when we on the ground
Under the lights and we walking around
Gonna gonna, it don't matter, my love for you is incurable
Can't nobody, take us anywhere, cause we all on the same thing
