[Verse 1]
C B7 Em (repeating)
I know what you did last summer,
C B7 Em
You told me not to tell a soul,
C B7 Em
Well if you broke your promise, then so can I,
C B7 Em
And I think it's time the whole world knows,
C B7 Em
Knows, that I think it's time the whole world knows,
[Chorus]
C B7 Em
See, I don't love you baby, but I need you to know,
C B7 Em
That you might think you're cool, but I'm in control,
C B7 Em
And yes she may be pretty, but I've got it all,
C B7 Em
So why you tryin' to keep it down low, down low,
C B7 Em
No, why you tryin' to keep it down low,
C B7 Em
Ooo-oooh-ooh-oooh-ooh,
