She and The Diamonds.

Every boyfriend is the one until otherwise proven
The good are never easy, the easy never good
And love it never happens like you think it really should
Deception and perfection are wonderful traits
One will breed love, the other hate
You'll find me in the lonely hearts
Under "I'm after a brand new start"
And I don't belong to anyone!

Girls and their curls and their gourmet vomit
Boys and their toys and their 6 inch rockets
We're all very lovely 'till we get to know each other
As we stop becoming friends and we start becoming lovers

I'm only happy when I'm on the run
I break a million hearts just for fun

I guess you could say that my life's a mess
But I'm still looking pretty in this dress
I'm the image of deception

When everything is life and death
You may feel like there's nothing left
Instead of love and trust and laughter
What you get is happy never after
But deep down all you want is love
The pure kind we all dream of
But we cannot escape the past
So you and I will never last...
