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 keeping us apart
He's really good at making me the villain
He knows I see him

Can somebody tell me how
To break your best friends heart if I don't tell her?
Who's gonna tell her?

He's superbad 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 superbad for her

He's telling her that she's the only one
Tell me how to tell her how to leave him
She doesn't need him (oh)
If someone that you loved was so in love
But you knew a dirty little secret
Would you keep it? (Oh)

Can somebody tell me how
To break your best friends heart if I don't tell her?
Who's gonna tell her?

He's superbad 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 superbad for her

Ah, ah, oh, ah, oh

Can somebody tell me how
To break your best friends heart if I don't tell her?
Who's gonna tell her?

He's superbad 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 superbad for her
