[Chorus: Avril Lavigne]
Am I insane expecting you to change?
It's the same thing over and over again
Déjà vu
It's time to act your age
It's the same thing over and over again
Déjà vu

[Verse 1: Avril Lavigne]
Just admit it, you're an asshole, living in a castle
You think you're better than everyone
But you can't buy me with something shiny
'Cause I am not like everyone

[Pre-Chorus: Avril Lavigne]
I think I've had it, enough of your bullshit
You're not romantic, you for sure are hopeless
I'll buy a Range Rover just to run you over and call you out

[Chorus: Christina Aguilera]
Am I insane expеcting you to change?
It's the same thing ovеr and over again
Déjà vu
It's time to act your age
It's the same thing over and over again
Déjà vu
Pills and alcohol
Excuses, yeah, I've heard them all
Insane, expecting you to change
It's the same thing over and over again
Déjà vu

[Post-Chorus: Avril Lavigne (Christina Aguilera)]
Oh-oh, oh-oh (Over and over with you)
Déjà vu
Oh-oh, oh-oh (Over and over with you)

[Verse 2: Christina Aguilera]
You think that the number inside of your bank account
Is the way into my heart
They say you're a saint, but you act like a sinner
Yeah, I should've known right from the start

[Pre-Chorus: Christina Aguilera]
But I think I've had it, enough of emotions
You're not romantic, you for sure are hopeless
When in doubt, I'll take a picture of us and I'll cut you out
[Chorus: Avril Lavigne with Christina Aguilera, Both]
Am I insane expecting you to change?
It's the same thing over and over again
Déjà vu
It's time to act your age
It's the same thing over and over again
Déjà vu
Pills and alcohol
Excuses, yeah, I've heard them all
Insane, expecting you to change
It's the same thing over and over again
Déjà vu

[Bridge: Avril Lavigne & Christina Aguilera]
I've seen this all a thousand times (A thousand times)
Stuck in the memory
I can't go back and change your mind (Can't change your mind)
Why does this keep happening?
Right time, wrong situation
Was all my love wasted?
I've seen this all a thousand times (Too many times)

[Chorus: Avril Lavigne with Christina Aguilera, Both]
Am I insane expecting you to change?
It's the same thing over and over again
Déjà vu
It's time to act your age
It's the same thing over and over again
Déjà vu
Pills and alcohol
Excuses, yeah, I've heard them all
Insane, expecting you to change
It's the same thing over and over again
Déjà vu
[Post-Chorus: Avril Lavigne with Christina Aguilera, Both]
Oh-oh, oh-oh (Over and over with you)
Déjà vu
Whoa-oh, whoa-oh (Over and over with you)
Déjà vu
