She walks in, you stop talking

I can see it all over your face

You still get defensive

Every time somebody brings up her name

And I could tell you that I don't see it

You could swear that you mean it

When you say you don't want no one else

But baby you been lying to yourself

Cause she's still the one in your head

I'm just the girl in your bed

She's got a hold of your heart

I'm just the one in your arms

When you're with me, you ain't with me

I feel her name on your lips when you kiss me, it kills me

You're gonna end up with her in the end

Cause she's your girl, I'm just your girlfriend

Heart don't lie, and neither do I

I don't wanna be second place

So when that day comes, and she calls and you run

I ain't gonna beg you to stay

But damn I wish that you had never met her

Wish there was a way I could make you forget her

Cause she's still the one in your head

I'm just the girl in your bed

She's got a hold of your heart

I'm just the one in your arms

When you're with me, you ain't with me

I feel her name on your lips when you kiss me, it kills me

You're gonna end up with her in the end

Cause she's your girl, I'm just your girlfriend

She's still the one in your head

I'm just the girl in your bed

She's got a hold of your heart

I'm just the one in your arms

When you're with me, you ain't with me

I feel her name on your lips when you kiss me, it kills me

You're gonna end up with her in the end

Cause she's your girl, I'm just your girlfriend

She's your girl, I'm just your girlfriend

Oh yeah

She's your girl, I'm just your girlfriend
