[Verse 1: Katy Perry]
Do you ever feel like a plastic bag
Drifting through the wind, wanting to start again?
Do you ever feel, feel so paper-thin
Like a house of cards, one blow from caving in?
Do you ever feel already buried deep?
Six feet under screams, but no one seems to hear a thing
Do you know that there's still a chance for you?
'Cause there's a spark in you

[Pre-Chorus: Katy Perry]
You just gotta ignite the light
And let it shine
Just own the night
Like the Fourth of July

[Chorus: Katy Perry & Kacey Musgraves]
'Cause baby, you're a firework
Come on show 'em what you're worth
Make 'em go, "Aah, aah, aah"
As you shoot across the sky
Baby, you're a firework
Comе on, let your colors burst
Make 'em go, "Aah, aah, aah"
You'rе gonna leave them all in awe, awe, awe

[Verse 2: Kacey Musgraves]
You don't have to feel like a waste of space
You're original, cannot be replaced
If you only knew what the future holds
After a hurricane comes a rainbow
Maybe a reason why all the doors are closed
So you could open one that leads you to the perfect road
Like a lightning bolt, your heart will glow
And when it's time, you'll know

[Pre-Chorus: Kacey Musgraves]
You just gotta ignite the light
And let it shine
Just own the night
Like the Fourth of July

[Chorus: Katy Perry & Kacey Musgraves]
'Cause baby, you're a firework
Come on, show 'em what you're worth
Make 'em go, "Aah, aah, aah"
As you shoot across the sky
Baby, you're a firework
Come on, let your colors burst
Make 'em go, "Aah, aah, aah"
You're gonna leave them all in awe, awe, awe

[Bridge: Katy Perry & Kacey Musgraves]
Boom, boom, boom
Even brighter than the moon, moon, moon
It's always been inside of you, you, you
And now it's time to let it through

[Chorus: Katy Perry & Kacey Musgraves]
'Cause baby, you're a firework
Come on, show 'em what you're worth
Make 'em go, "Aah, aah, aah"
As you shoot across the sky
Baby, you're a firework
Come on, let your colors burst
Make 'em go, "Aah, aah, aah"
You're gonna leave them all in awe, awe, awe

[Outro: Katy Perry & Kacey Musgraves]
Boom, boom, boom
Even brighter than the moon, moon, moon
Boom, boom, boom
Even brighter than the moon, moon, moon
