[Verse 1]
I've been up for twenty-four hours
Calling out your name in the shower
Oh, God, might be pathetic
But I don't fucking care right now

[Pre-Chorus]
I know you're gonna tell your friends it ended fine
But then, oh, I kinda went and lost my mind

[Chorus]
I'm that crazy ex in red stilettos
Acting like we're still together
Shit, I guess I missed the memo
I'm that psycho bitch you can't get rid of
Sends your new girl naked pictures
Do it all because I'm bitter
I'm that crazy ex

[Verse 2]
I know every place that you've been
'Cause I still got your location
You don't know that I'm in the back
Of the bar while you're doing your shots with her

[Pre-Chorus]
I know you're gonna move on thinking it's all fine
But then, oh, I'm gonna turn up in the middle of the night
[Chorus]
I'm that crazy ex in red stilettos
Acting like we're still together
Shit, I guess I missed the memo
I'm that psycho bitch you can't get rid of
Sends your new girl naked pictures
Do it all because I'm bitter

[Bridge]
Showing up at your door, 2 a.m.​
Picking your lock in a wedding dress
Lay in your bed like a psychopath
Waiting for you to come home

[Chorus]
I'm that crazy ex that loved you better
Acting like we're still together
Shit, I guess I missed the memo
I'm that psycho bitch you can't get rid of
Sends your new girl naked pictures
Do it all because I'm bitter

[Outro]
I'm that crazy ex (Oh, oh)
I'm that crazy ex (Oh, oh)
I'm that crazy ex (Oh, oh)
(Showing up at your door, 2 a.m.)
I'm that crazy ex (Oh, oh)
(Lay in your bed like a psychopath)
I'm that crazy ex
