The humiliating flub occurred live on Fox on Sunday night and wasn't caught until after Ariadna Gutierrez Arevalo of Colombia was already wearing the glittering crown.
Harvey explained he'd simply read incorrectly from the card, which he held up to the cameras to show that Pia Alonzo Wurtzbach of the Philippines was this year's winner and Colombia was the first runner-up.

All wrongs appeared to be righted. Unfortunately, Steve Harvey had another mistake or two to make.

In the 7 p.m. tweet, which has since been corrected but is still visible at the New York Daily News, Harvey wrote: "I want to apologize emphatically to Miss Philippians and Miss Columbia. This was a terribly honest human mistake and I am so regretful."
Harvey soon posted an updated apology to "Miss Colombia & Miss Philippines."
Mark Shapiro, an executive with pageant owner WME-IMG, told reporters that Harvey caught the mistake himself. "It was humiliating for the women. It was humiliating for him," Shapiro said.
The previous owner of the pageant, none other than Republican presidential front-runner Donald Trump, pounced on the opportunity to tout his leadership skills.
