Former “Bad Girls Club” star Christina Hopkins has been BANNED from appearing on the Oxygen network EVER AGAIN following her vile, racist rant … TMZ has confirmed.

A rep for Oxygen tells us, “Oxygen condemns those comments… she will never appear on Oxygen again.”

TMZ broke the story … Hopkins unleashed a disgusting, racist rant directed towards an African-American woman last month — dropping the N-word 12 times in less than 90 seconds.

Hopkins later apologized — saying the rant “wasn’t meant in a derogatory way.”
