People think Simone Biles may have just 'leaked the biggest gymnastics secret' ever

Gymnast Simone Biles may have unknowingly 'leaked the biggest gymnastics secret' ever in one of her latest videos.

The Team US four-time Olympic gold medallist may have slipped up as she made a TikTok with some of her gymnast teammates, and social media users were quick to clock on.

If you haven't seen it already, prepare to get your mind blown - this is truly ground-breaking stuff.

Biles became the fourth American female artistic gymnast to compete at the Olympics, while already being looked at as one of the greatest gymnasts of all-time.

But it looks like she isn't at skills at keeping secrets of the sport under wraps, as her simple TikTok video has gone viral for unveiling a well-kept secret.

See if you can spot the giveaway in her video:

The 27-year-old's TikTok has since been stitched by Ian Gunther, a fellow gymnast who posts daily content related to the sport on the social media app.

He starts by explaining that the athlete has leaked 'the biggest gymnastics secret' as you are able to see a 'gymnastics spotter' in the background of the video in question.

It's news that will surely rock the sporting world, as Gunther goes on to explain that these spotters, dressed from head to toe in green, train meticulously for months to help gymnasts maintain their positions, spotting them without being seen - obviously because green can be edited out on TV and people in the arena are blind.

It's no wonder they're able to pull off all of the moves and flips that they attempt.

Gunther even uncovered footage of the green men warming up, confirming the rumour for good, while (not so hidden) footage was also released of US gymnastics coach Laurent Landi speaking to the spotters.

"Good luck today, be safe, make sure to keep our athletes safe, and please don't be seen," he instructed the spotters.

If you haven't realised already, the entire video is a parody, making fun of those who doubt gymnasts and highlighting how difficult the sport really is.

"All the gymnastics you see being done is actually impossible and it's all done by spotters," Gunther sarcastically explained.

Apparently (not really), the green men practice 'for months' so that they can make the performance look 'as real as possible', while not getting seen.

Gunther explains that because the audience want the gymnasts to do more 'demanding' things on the floor, the professionals have had no choice but to hire spotters.

The video hilariously ends with the words, 'GYMNASTICS ISN'T REAL'.

Viewers took to the comments section to make some jokes about the 'revelation'.

One user joked: "What about people who watch it in person do they not see them or something?"

A second posted: "As a gymnast this is true and they help me every day"

A third highlighted: "GUYS HE JOKINNN"

A different user revealed: "As a gymnast I can confirm. There was a huge scandal at a meet a few years ago when a spotter pushed a girl off the beam bc they used to hook-up but she swapped him for a diff spotter."

Scandalous stuff - if it was real, of course.
