She don't

[Dood.]

Hello,

I was listening to some music when I heard "she don't..." instead of "she doesn't". I'm pretty sure that I already heard that from someone in the street.
I googled a bit and found some interesting threads where one was saying that it is not Standard English when another thought that it actually was a kind of dialect that you can associate to Standard English.
Where is the truth, dear Members and Teachers ?

Thanks for your answers :}

It's not standard English.

There may be dialects where it's common (well, there ARE dialects where it's common), but "standard" it is not.
