Lyrics

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
How to be a heartbreaker
Boys they like the look of danger
We'll get him falling for a stranger
A player, singing lo-lo-love you
At least I think I do

Cause I lo-lo-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
Kissing goodbye at the door, and leave him wanting more

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
How to be a heartbreaker
Boys they like the look of danger
We'll get him falling for a stranger
A player, singing lo-lo-love you
At least I think I do

Cause I lo-lo-love you

Girls, we do, whatever it will take
Cause girls don't want, we don't want our hearts to break in two
So it's better to be fake, can't risk blue
Sinning love again rain

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
How to be a heartbreaker
Boys they like the look of danger
We'll get him falling for a stranger
A player, singing lo-lo-love you

Cause I lo-lo-love you

At least I think I do
