[Verse 1]
I am done, smoking gun
We've lost it all, the love is gone
She has won, now it's no fun
We've lost it all, the love is gone

[Pre-Chorus]
And we had magic
And this is tragic
You couldn't keep your hands to yourself

[Chorus]
I feel like our world's been infected (Ahh)
And somehow, you left me neglected (Ooo)
We've found our lives been changed (Ooo)
Babe, you lost me

[Verse 2]
And we tried, oh, how we cried
We lost ourselves, the love has died
And though we tried, you can't deny
We're left as shells, we lost the fight

[Pre-Chorus]
And we had magic (Ooo)
And this is tragic (Ooo)
You couldn't keep your hands to yourself, woah

[Chorus]
I feel like our world's been infected (Ooo)
And somehow you left me neglected (Ooo)
We've found our lives been changed (Ooo)
Babe, you lost me

[Bridge]
Now I know you're sorry and we were sweet (Ahh, ahh)
But you chose lust when you deceived me (Ahh, ahh)
And you'll regret it, but it's too late (Ahh, ahh)
How can I ever trust you again? (Ahh)

[Chorus]
I feel like our world's been infected (Ooo)
And somehow you left me neglected (Ooo)
We've found our lives been changed
Babe, you lost me
