[Verse 1]
Sometimes at night
When I turn off the lights
I be thinking about you
Baby, baby, baby, yeah
Tossing in my bed
All these thoughts in my head
Got me losing my breath now
Baby, baby, baby, yeah

[Pre-Chorus]
Tell me what would you do (eh-eh-eh)
If you only knew (eh-eh-eh)
How I feel about you
About you-ou

[Chorus]
I wanna be first, your last, your everything
I wanna be in your arms indefinitely
I wanna be someone you keep coming back to see
I wanna be what (eh-eh-eh)
I wanna be who (eh-eh-eh)
Wanna be your baby

[Verse 2]
Deep down inside
There's an unending fire
And I just can't contain it
Baby, baby, baby, yeah
You're the only one who can
Show me that you feel the same
I wanna hear you say my name
Baby, baby, baby, yeah
[Pre-Chorus]
Tell me what would you do (eh-eh-eh)
If you only knew (eh-eh-eh)
How I feel about you
About you, you, you

[Chorus]
I wanna be first (yeah), your last, your everything (I wanna be)
I wanna be in (in) your arms (arms) indefinitely (oh-oh-oh)
I wanna be someone you keep coming back to see
I wanna be what (eh-eh-eh)
I wanna be who (eh-eh-eh)
Wanna be your baby

[Breakdown]
Hoo-hoo-hoo
Hoo-hoo
Hoo-hoo-hoo
Hoo-hoo

[Chorus]
I wanna be first (first), your last (last), your everything
I wanna be in (in) your arms (your arms) indefinitely (yeah-yeah-yeah)
I wanna be someone you keep (you keep) coming back to see (see)
I wanna be what (eh-eh-eh)
I wanna be who (eh-eh-eh)
I wanna be your baby-yeah-yay
[Outro]
I wanna be your baby
Baby, baby, baby-yeah-yeah-yaaay
Ooh yay
Ooh yay, hey-by
Ba-by
Ay-yay
