Mireia Lalaguna let slip during a TV interview that her introduction video, which sees her playing the piano, was actually a montage - and she was not really playing the music at all.
The beauty queen can be seen at the instrument while a voice-over describes how she has played the piano since she was a child, making the judges think it was her playing the score.
To her dismay, the delighted judges after watching the video asked former Miss Spain Mireia to play the same music live the next day for university students.
In a tight spot, she had no other option but to say yes, but luckily for her, the performance was cancelled, and she got away with it.
"It’s out little secret, I cheated a bit – but hey I already have the crown", she joked on the show.
The pharmacy student also described her life following the contest saying: "I am getting used to the attention, some people see me as some kind of Goddess, but look I’m human and here with you all tonight."
She will now go on a tour through the United States and Canada, before heading off to Kenya next month to take part in humanitarian work, which she is passionate about.
"It is not just about beauty; I want to raise the most amount of money possible to help these social projects."
Mireia was crowned Miss World 2015 on December 21 2015 in Sanya, China, the 54th young lady to win the title.
