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)
