Girl On Fire (Extended) [Live From Movistar Arena Santiago, Chile] lyrics

[Chorus]
This girl is on fire (Ooh, fire, fire, yeah)
This girl is on fire
She's walkin' on fire (Chile, fire, fire)
This girl is on fire, help us, help us (Ooh)

[Post-Chorus]
Oh-oh (Santiago), oh, oh
Oh-oh, oh, oh (Ooh-ooh)
Oh-oh, oh, oh
Oh-oh, oh, oh (Oh)

[Outro]
My sister
