You got me -

Baby I, I
wanna be the girl that gives you everything
My whole heart, every piece, every part of me
And I'm gon' do my best
to make sure that you never leave
And boy, you do your best
cause you're the reason that I breathe
And sometimes we gon' fight
but at the end of the night I humble myself
baby, we're alright
Make sure that we're tight
Your love is my muse
No more will I have to choose
You're my number one, there's no number two
