The American gymnast made a rare mistake on the beam as she missed out on Olympic gold.

Simone Biles appeared to complain about the crowd inside Paris’ Bercy Arena after she missed out on a  medal in the gymnastics beam final.

The 27-year-old, who is widely regarded as the greatest gymnast of all time, was expected to claim another gold medal in Monday’s beam final.

So far, she has stormed to an unprecedented three gold  medals in Paris and recently produced more brilliance in the individual women’s vault.

But days later, she made an uncharacteristic error after making a strong start to her routine. Biles proceeded to fall off the beam half way through, which prompted a number of gasps from the crowd.

The American regained her composure after the fall to complete the beam routine and earn a score of 13.100.

That being said, Biles was far from happy with the circumstances surrounding the fall. In fact, when she re-joined her coach and teammates at the seating area, she complained about the crowd inside Paris’ Bercy Arena.

Widespread reports suggest Biles accused them of making unnecessary noises as she took to the beam.

Throwing her hands in the air, it appears she told them to “stop shushing” before adding: “Why are they all shushing? As soon as I’m going they’re like shushing so much.”

USA teammate Sunisa Lee replied: “I don’t know why, are they [the Olympic gymnastics organisers] telling them to?”

It appears shouts of “come on Simone” were heard while she performed, which brought “shush” sounds from people in the audience. You can watch the events unfold below:

Craig Heap, the BBC commentator who was reporting on the event, said he’d “never seen Simone Biles look so angry” in his life.

“She was not happy. Something has gone on in the arena,” he said.

“Simone is not happy at all. It just goes to show she is a human being. All the other ladies in that final have made mistakes. She’s not invincible.’

Heap’s co-commentator Matt Baker clarified: “She’s talking about the atmosphere. She’s talking about shushing. The feeling in here is like a cauldron when the gymnasts are on. Oh my word.”

After losing her balance at the end of an aerial series, Biles placed fifth.

Italy’s Alice D’Amato deservedly won gold with a score 14.366, whilst China’s Zhou Yaqin took home a silver  medal with 14.100. Manila Esposito of Italy picked up the bronze with 14.000.
