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

How to be a heartbreaker
People like a little danger
We'll get him falling for a stranger, a player
Singing I love you

Rule number three, wear your heart on your cheek
But never on your sleeve, unless you wanna taste defeat
Rule number four, gotta be looking pure
Kiss them goodbye at the door and leave them wanting more

These are the rules of heartbreaking
'Cause people like a little danger
We got them to fall for a stranger, a player
That sang I Love You
