[Charli XCX:]
I-I-I-it's a knife when you know they're waitin' for you to choke
It's a knife when a journalist does a misquote
It's a knife when a friend is suddenly steppin' on your throat
It's a kni-i-ife when they say that you've been doing things you don't-don't-don't

It's a knife when your old friends hate your new friends
When somebody says, "Charli, I think you've totally changed."
It's a knife when somebody says they like the old me and not the new me
And I'm like, "Who the f**k is she?"

'Cause it's a knife when you're finally on top

It's a knife when you're finally on top (On top)
'Cause logically the next step is they wanna see you fall-fall-fall

I-I-I-it's a knife when, it's a knife when, it's a knife when (When, when, when)
All this sympathy is just a knife when (When, when, when)
It's a knife when, it's a knife when (When, when, when)

[Ariana Grande:]
It's a knife when you know they're counting on your mistakes
It's a knife when you're so pretty, they think you must be fake (Mm)
It's a knife when they dissect your body on the front page (Mm, ooh)
It's a knife when they won't believe you. Why should you explain? (Yeah)

It's a knife when the mean fans hate the nice fans
When somebody says, "Ari, I think you've totally changed." (No sh*t)
(It's a knife) When somebody says they like the old me and not the new me
And I'm like, "Ha-ha, who the f**k is she?"
