Representing the central Spanish province of Caceres was contestant Pilar Magro.
In the clip which has now gone viral, Pilar, along with other contestants line-up beside a swimming pool and take it in turns to walk in front of the judges.
The woman before Pila walks confidently in her high heels, and with the competition high it’s soon Pila’s turn to give everything she’s got.
In attempt to impress she decides to perform a twirl during her walk.
But all doesn’t quite go to plan.
As she approaches the judging panel, Pila places her hands on her hips and does a quick turn.
Unfortunately she performs the manoeuvre too close to the side of the pool.
Before she even has time to complete the 360 degree spin, she slips into the water.
Pila’s full body plunges into the pool and the girls behind rush to see how she is.
The slip-up may have cost Magro the titles as it was eventually given to Sofia del Prado of Castilla La Mancha.
The video was uploaded to Imgur and users were quick to comment.
One joked: “Taking the swimsuit competition up a notch.”
