Marina and the Diamonds — How to be a heartbreaker

Rule number one, is that you gotta have fun
But baby when you're done, you gotta be the first to run
Rule number two, just don't get attached to
Somebody you could lose
So le-le-let me tell you

This is how to be a heartbreaker
Boys they like a little danger
We'll get him falling for a stranger
A player, singing lo-lo-love you
