Miss Universe Colombia contestant Ariadna Gutierrez mistakenly announced as the winner of Miss Universe.
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.
