[Verse 1: Nick Jonas]
One, two, three, elementary
I need you, I got no plan B
You're my girl
You're my girl
Four, five, six, no magical tricks
Mint condition getting my fix
You're my girl
You're my girl

[Pre-Chorus: Nick Jonas]
You can turn me on like a TV, strutting through the city
Making me sweat, you make it look easy
The beat of my heart, the beat that won't leave me
My girl

[Chorus: Nick Jonas & Joe Jonas]
You're unbelievable, baby, how you do it like that?
You walk by and give the world whiplash
Mercy, mercy, mercy, mercy
Mercy, mercy, girl
You're unbelievable, shining, makе a diamond get mad
You show up and make the wholе room clap
Mercy, mercy, mercy, mercy
Mercy, mercy, girl
You're unbelievable
[Verse 2: Nick Jonas & (Joe Jonas)]
She don't try hard
Dance and don't think
Loves karaoke, says, she can't sing "My Girl" (My Girl)
I'm talking 'bout my girl

[Pre-Chorus: Nick Jonas & Joe Jonas, (Nick Jonas)]
You can turn me on like a TV, strutting through the city
Making me sweat, you make it look easy
The beat of my heart, the beat that won't leave me
My girl (My girl, my girl)

[Chorus: Nick Jonas & Joe Jonas]
You're unbelievable, baby, how you do it like that?
You walk by and give the world whiplash
Mercy, mercy, mercy, mercy
Mercy, mercy, girl
You're unbelievable, shining, make a diamond get mad
You show up and make the whole room clap
Mercy, mercy, mercy, mercy (Oh yeah)
Mercy, mercy, girl
You're unbelievable

[Bridge: Joe Jonas]
You're unbelievable
[Pre-Chorus: Nick Jonas & Joe Jonas, (Nick Jonas)]
You can turn me on like a TV, strutting through the city
Making me sweat, you make it look easy
The beat of my heart, the beat that won't leave me
My girl (My girl, my girl)

[Chorus: Joe Jonas with Nick Jonas]
You're unbelievable, baby, how you do it like that?
