Taraji jokingly asked Nia if she was on her period after she went nuts on a fellow cast member and that’s what set off their raging feud on the set of “Empire.

Nia showed up late shortly after beginning her stint on the show, prompting one of the male actors to joke, “Damn, why are you on black people time?”

We’re told that sent Nia into a rage – chewing the guy out.
