People horrified after man is forced to watch video of his girlfriend cheating on him

People have been left absolutely reeling after seeing a man being made to watch a video of his girlfriend cheating on him.

A clip from the Spanish reality TV series La Isla de las Tentaciones, based on the American series Temptation Island, has been doing the rounds on social media at the moment - and there's very good reason why.

Now, the premise of the show sees couples go to a tropical island where they are split up and live in a house with single people who try to get them to have affairs.

And, unsurprisingly, there's a whole load of drama.

While the US version of the show ended back in 2003, the Spanish show is in its eight season.

The latest season has now gone viral due to contestant José Carlos Montoya's reaction to seeing his partner do the deed with another bloke right in front of him.

It all began when Montoya was taken away from the resort by host Sandra Barneda.

Now, earlier in the series, his girlfriend, Anita Williams, was made to watch him participate in a challenge where he receives a lap dance and a strip tease.

Clearly annoyed by the ordeal, she then started getting flirty with another dude in the villa - Manuel - for revenge.

It all came to a boiling point when Montoya was taken away to a beach to watch Anita in a room with Manuel while they started kissing in bed, before eventually doing the business.

Understandably, Montoya screaming out in agony at the situation as he falls to his knees and starts crying.

Clearly figuring out what events are about to ensue under the sheets between Anita and Manuel, Montoya then paces it across the beach to the villa while repeatedly shouting, as the host tried her best in keeping Montoya calm, running after him shouting: "Montoya, por favor!"

The whole thing makes for some seriously good telly.

People have since rushed to social media to share their reactions to the viral clip which is arguably of the most dramatic moments in reality TV history.

One Twitter user urged: "Please everyone put on Spain’s Temptation Island tonight!! This was last nights episode and I promise you don’t need subtitles to enjoy pure CINEMA."

"This is CINEMA…Montoya..the tension… you don’t need to speak Spanish to understand, this is insane," quipped a second.

A third chimed in: "OMFGGAGSGS THE SPANISH VERSION OF TEMPTATION ISLAND IS GAGGY????

"They showed him a clip of his gf cheating on him and he ran to the women’s villa to confront her meanwhile she’s getting railed."

"Temptation Island is peak reality TV it's up there," chirped a fourth, while a fifth piped up: "Is anyone else seeing clips of the Spanish Temptation Island? It looks chaotic and I NEED to watch it!"

A sixth confessed: "I actually love Temptation Island. I watch every season it’s amazing television but no one has ever ran across the sand to stop their partner from getting put through a mattress that is pure cinema."
