[Verse 1: Kelsea Ballerini]

I bet you're from out west somewhere

Hazel eyes and dark brown hair

And everything you wear fits you just right

I bet you drink martinis dry

And never let 'em see you cry

I bet you're more promiscuous than I

[Pre-Chorus: Kelsea Ballerini & Halsey]

I bet you're bold, I bet that's why you seem to occupy his mind

I bet you're smart, but do you know about me? (Is it you?)

[Chorus: Kelsea Ballerini]

Is it me? Is it you?

Tell me who, who's the other girl?

Who's the first? Who's the fool?

Who's the diamond? Who's the pearl?

Are you mad? Me too

And I wonder, in his world

Is it me? Is it you?

Who's the other girl?

[Post-Chorus: Kelsea Ballerini & Halsey, Kelsea Ballerini & Halsey]

Who's gonna put on the red dress

Scarlet letter on her chest

Can't love with this on her conscience

Tell me, who's the other girl, girl, girl, girl?

[Verse 2: Halsey & Kelsea Ballerini]

Are you the one he's talkin' to

When he gets up and leaves the room

And comes back with a distance in his eyes? (Ah)

Maybe I should be the one to leave

But damn, when he starts lovin' me

It makes me think I'm all that's on his mind (Ah, ah)

[Chorus: Halsey]

Is it me? Is it you?

Tell me who, who's the other girl?

Who's the first? Who's the fool?

Who's the diamond? Who's the pearl?

Are you mad? Me too

And I wonder, in his world

Is it me? Is it you?

Who's the other girl?

[Post-Chorus: Kelsea Ballerini & Halsey, Kelsea Ballerini & Halsey]

Who's gonna put on the red dress

Scarlet letter on her chest

Can't love with this on her conscience

Tell me, who's the other girl, girl, girl, girl?

[Bridge: Halsey & Kelsea Ballerini]

I bet you're cool, I bet that's why you seem to occupy his time

I bet by now, you know about me (And you know about me)

[Chorus: Kelsea Ballerini & Halsey, Kelsea Ballerini, Halsey]

Is it me? (Is it me?) Is it you? (Is it you?)

Tell me who, who's the other girl?

Who's the first? (Who's the first?) Who's the fool? (Who's the fool? Yeah)

Who's the diamond? Who's the pearl?

Are you mad? (Are you mad?) Me too (Me too)

And I wonder, in his world

Is it me? (Is it me?) Is it you? (Is it you?)

Who's the other girl?

[Post-Chorus: Kelsea Ballerini & Halsey, Kelsea Ballerini & Halsey]

Who's gonna put on the red dress

Scarlet letter on her chest

Can't love with this on her conscience

Tell me, who's the other girl, girl, girl, girl?
