Here's from an old song (1963) "[She's A Fool](http://www.lyricsfreak.com/l/lesley+gore/shes+a+fool_20212286.html)" by Lesley Gore. 

> 
> **She don't know** that she's a lucky girl
> 
> 
> 

Here's another example, "Silence is Golden" (1964) by The Tremeloes  

[YouTube [link](https://www.youtube.com/watch?v=n03g8nsaBro)] 

> 
> Oh, **don't it hurt** deep inside to see someone do something to her.
> 
> 
> 

I wonder how common it is to say "She don't" or "don't it".  

Do native English speakers often use these?

By the way, Lesley Gore is American, and the Tremeloes is British.
