She says she isn't even going to sue him, as some lawyers have suggested.
But she does have some advice for the television host.
"You need to learn how to read cards," Ariadna Gutierrez joked with Harvey during an appearance on his talk show scheduled to air Tuesday.
During the finale of the December 20 Miss Universe Pageant, Harvey misread the card listing the winner and runners-up; he announced Gutierrez as the winner.
Pageant judges had intended for Miss Philippines, Pia Wurtzbach, to win.
Harvey's gaffe resulted in an intensely awkward moment in which the crown was taken from Gutierrez and placed on Wurtzbach.
"If you see the videos, I was laughing because I thought you were about to make a joke," she said.
"That would have been the worst damn joke I ever wrote in my life," Harvey shot back.
Gutierrez says the experience felt like a "nightmare" and revealed that several lawyers contacted her, suggesting that she sue.
"That's not me," she said. "That's not who I am."
She says she's moved on now.
"This is our destiny," she said.
Harvey, who appeared emotional at times, said the gaffe wasn't a publicity stunt, as some have theorized. He also revealed that he had received death threats over the mistake.
Tuesday's show is the second part of a two-part special. Monday's episode featured Wurtzbach.
"I was very happy that I won; I was excited," she told Harvey. "But I was also thinking about (Gutierrez). I couldn't help but think about how tough this must be for her."
