Madonna showed up at the Grammy Awards with her son David Ritchie -- the one she did NOT call the n-word ... and the one who just happens to be African.

They even wore matching tuxes.
Of course Madonna apologized for using the n-word, saying it was not meant as a racial slur, and was intended to be a "term of endearment" to Rocco.
But c'mon, we gotta ask ...
