Rachel Dolezal made a huge confession, and while it shocked absolutely no one ... it was still cool to finally hear her say it -- SHE'S WHITE.

The former prez of the NAACP's Spokane chapter was on "The Real" doing her usual tap dance about "identifying as black" and blah, blah, blah. But we gotta hand it to co-host Jeannie Mai, who just put it to Dolezal straight, telling her ... "You're NOT black."
