I don't wanna break her little heart
But I know his dirty little secret
Would she believe me or would she believe him?
He's really good at keepin' us apart
He's really good at makin' me the fill-in
He knows I see him
Can somebody tell me how to break your best friend's heart?
If I don't tell her, who's gonna tell her?
He's super bad for her
This will end badly and she will get hurt
She's super madly in love
He'll cheat on her and then he'll kill the messenger
I'm super sad 'cause he's super bad for her (bad)
He's tellin' her that she's the only one
Tell me how to tell her how to leave him
She doesn't need him (oh, oh)
Someone that you love was so in love
But you knew a dirty little secret
Would you keep it? (Oh, oh)
Can somebody tell me how to break your best friend's heart?
If I don't tell her, who's gonna tell her?
He's super bad for her
This will end badly and she will get hurt
She's super madly in love
He'll cheat on her and then he'll kill the messenger
I'm super sad 'cause he's super bad for her (bad)
Oh, oh, oh-oh, oh, oh-oh
Can somebody tell me how to break your best friend's heart (oh, oh, oh-oh, oh, oh-oh)
If I don't tell her, who's gonna tell her?
He's super bad for her
This will end badly and she will get hurt
She's super madly in love
He'll cheat on her and then he'll kill the messenger
I'm super sad 'cause he's super bad for her (bad)
