The host of the Miss Universe has apologised after mistakenly naming the wrong woman as winner, leaving Miss Colombia empty-handed.
After the error, Ariadna Gutierrez was instead declared runner-up and surrendered her crown to Miss Philippines, Pia Alonzo Wurtzbach.
#MissUniverse2015 became Twitter's biggest trend of the night as social media users expressed their disbelief.
Ms Wurtzbach has since told reporters that she wishes Ms Gutierrez well.
"I'm very sorry, I did not take the crown away from her and I wish her well in whatever she wants to pursue after this pageant," she said.
Ms Gutierrez also addressed fans in a backstage video that has been shared on the pageant's official page.
She said: "Everything happens for a reason so I'm happy for all that I did."
At the end of the night in Las Vegas, Ms Gutierrez was named first runner-up followed by Olivia Jordan from the United States.
