If I was your girlfriend, I'd drive you up the wall
Question who you're with
Yeah, I'll always call and call
I wouldn't call it jealousy, just looking out for you
Reading all your texts
Watching everything you do

Nag, nag, nag on you
Ask all about your past and Facebook stalk you too
I don't care about them, I just care about us
So, say hello to a girlfriend you should trust, trust, yeah

I'll always be checking up on you
Hey, boy, who you talking to?
If I was your girlfriend

I'd never let you leave
Without a small recording device taped under your sleeve
And you'll only look your best and shave your face for me
Don't hide secrets in your house, 'cause boy I stole the key

So tell me if you like her
Don't try to say you don't
I can see it in your eyes that you want to try and go
That ain't the right choice
Yeah, you already know
Imma make you stay with me and be mad if you don't

Gir- girlfriend, girlfriend
I will be your girlfriend
I will be your girlfriend
I WILL BE YOUR GIRLFRIEND.

I'll always be checking up on you
Hey, boy, who you talking to?
If I was your girlfriend

I'd never let you leave
Without a small recording device taped under your sleeve
And you'll only look your best and shave your face for me
Don't hide secrets in your house, 'cause boy I stole the key

I make wedding plans 'cause you'll stick with me
Boy, spend the day with your girl
I'll be calling you my husband
I just made a list, all our future kids' names
Bartholomew, Claire, and Steven Bryce

I'd never let you leave
Without a small recording device taped under your sleeve
And you'll only look your best and shave your face for me
Don't hide secrets in your house, 'cause boy I stole the key

Na na na, na na na, na na na, yeah, boy!
Na na na, na na na, na na na, yeah!
Na na na, na na na, na na na, yeah, boy!
Na na na, na na na, na na na
If I was your girlfriend
