Katy Perry - Takes One To Know One

What are you lookin' at (yeah)

I saw this coming, from a mile away
I saw a crack in the egg, a little rip in the page
I found your necklace, on the floor
Underneath the bed, where you said, I was the only one

You thought I'd cry (you thought I'd cry)
You thought I'd lay down and die
You thought, there's no getting over you (haha) And all this time (all this time)
You've been having, your fun
I've been having, some fun too

'Cause' it takes one to know one
Congrats, you've met your match
You think I'd lie here, heartbroken
But the knife, is in your back (in your back)

You left your suit, you left your tie and looked me in the eye
And swore that it, was business baby (yeah right)
And when you left, I got a call, that started it all
And now, it's not your business, baby

You thought I'd cry (you thought I'd cry)
You thought I'd lay down and die
You thought, there's no getting over you (haha)

But all this time (all this time)
You've been having, your fun
I've been having, some fun too

'Cause' it takes one to know one
Congrats, you've met your match
You think I'd lie here, heartbroken
But the knife, is in your back (in your back)

You're such a wreck, the cutest accident
Makes so much sense, you'll come back to me, ooohhh
And I'll let you
Hey, huh, you're back

'Cause' it takes one to know one
Congrats, you've met your match
You think I'd lie here, heartbroken
But the knife, is in your back (in your back)

'Cause' it takes one to know one (hi, nice to meet you)
Congrats, you've met your match
You think I'd lie here, heartbroken (I'd lie here)
But the knife, is in your back (in your back)
