NeNe Leakes thinks Donald Trump has changed for the worse since taking over the White House.

The reality TV star, who was a contestant on Season 4 of "The Apprentice" when Trump hosted, said on "The Dr. Oz Show" Wednesday that she doesn't recognize the man the nation now refers to as President Trump.

“When I worked for Donald, he and I got along very well … Now, who this person is that we’re seeing, I don’t know who that is... I don't know him to ever speak that way,” the "Real Housewives of Atlanta" star said.

“Now, he’s always been very honest and very true and very blunt,” she said. “He’s always been that way, but I did not witness him doing anything unethical.”

Trump, who served as the host of "The Apprentice" from 2004-2015, never actually got to drop his famous catchphrase, "You're fired!" on Leakes, as she removed herself from the competition before it could happen.

"I think I'm the only one that's ever quit the show," she said.

"The New Celebrity Apprentice" ended its season last month, and host Arnold Schwarzenegger stepped down after a back and fourth Twitter quarrel with Trump over the show's low ratings. Schwarzenegger took over Season 15 hosting duties to accommodate Trump's presidential campaign. There is no word yet on whether or not the show will continue.

“I loved every second of working with NBC and Mark Burnett,” Schwarzenegger said in a statement. “Everyone from the celebrities to the crew to the marketing department was a straight 10, and I would absolutely work with all of them again on a show that doesn’t have this baggage."
