[Verse 1]
If someone was to tell me back when I was 22
That a boy was gonna take my heart and break it
I would hand it to you
If someone were to warn me that this was gonna happen
That you would walk into my life and ruin it
I would still let you, hey

[Pre-Chorus 1]
I was young and blinded
By the pretty things that I have
Never seen before
You were new and shiny
I have never met somebody
Quite like you before

[Chorus]
Teenage heartbreak
It's a classic mistake
And I would do it again, do it again, do it again
I would do it again, yeah
Teenage heartbreak
It's a classic mistake
And I would do it again, do it again, do it again
I would do it again, yeah
[Verse 2]
If you were gonna lie to me and play with my emotions
And take everything in my possession
I would still want you
If you were gonna cheat on me with somebody else
And someone came and let me know about it
I'll believe you instead

[Pre-Chorus 2]
I feel like I'm 17 listening to everything you say
Boy, 'cause I love you, ooh
I think I was desperate
Just like a little kid in love
Thinking you love me too

[Chorus]
Teenage heartbreak
It's a classic mistake
And I would do it again, do it again, do it again
I would do it again, yeah
Teenage heartbreak
It's a classic mistake
And I would do it again, do it again, do it again
I would do it again, yeah
