Can you spot this major reality TV blunder?

Another day, another live television blunder.

As gymnastic act Acrocadabra took to the stage on Britain’s Got Talent on Wednesday night, they had an unexpected guest join them on the stage.

Of course, it wasn’t totally apparent to the naked eye, but some clever clogs on Twitter pointed out the mishap.

In one part of the act, a clever contortionist fits himself into a glass box, but the next minute he disappears.

However, as the cloth was pulled away from the box, a man who clearly wasn’t a part of the act was seen.

• Reality show judges left shocked by gatecrasher on live TV

• Is this the most awkward TV gaffe ever?

The man – who appeared to be a crew member – was definitely shocked as the cloth was pulled away.

Many viewers on social media were quick to point out the mishap.

One Twitter user also pointed out the poor bloke appeared to be mouthing, “What the f***?”.

Oh how we love a good TV blunder.
