Bm , A , G throughout the whole song. [Verse 1] 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-let me tell you [Chorus] This is how to be a heartbreaker Boys they like a little danger We'll get him falling for a stranger, a player Singing I 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 I lo-lo-love you At least I think I do! Cause I lo-lo-lo-love you. [Verse 2] 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 him goodbye at the door and leave him wanting more-more [Chorus] This is how to be a heartbreaker Boys they like a little danger We'll get him falling for a stranger, a player Singing I 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 I lo-lo-love you At least I think I do! Cause I lo-lo-lo-love you. [Bridge] 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 losing love again babe. [Chorus] This is how to be a heartbreaker Boys they like a little danger We'll get him falling for a stranger, a player Singing I 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 I lo-lo-love you Cause I lo-lo-lo-love you. At least I think I do!
