A video shared on social media has shown the brutal moment a nine-months pregnant woman caught her husband with his mistress on the beach.

The clip was recorded by the wife, who initially stands far away and films her unsuspecting spouse in the distance.

According to the Daily Mail, none of the three have been identified.

The TikTok video shows the indignant pregnant woman trudging across the sand and then ambushing her cheating husband and his mistress.

But when the wife surprises them, they both normal as the mistress remains lounging on the ground, completely calm.

With a smirk on her face, she looks up at the nine-months pregnant woman and doesn’t say anything.

At this point in the TikTok, which has over 13 million views, the dog wanders into the frame and wags its tail. The wife captioned the video: ‘He took my dog with him too.’

Before the clip ends, the cheating husband finally stands up.

In another TikTok, captioned ‘here’s the part two you’ve all been asking for,’ the confrontation is shown without music playing in the background.

‘Hey so who the f*** is this?’ the broken-hearted woman yells at the couple, interrupting their meet up.

‘I’m his nine-months pregnant wife. Who the f*** are you?’

‘His baby is right there,’ she says, in a strained voice.

Neither the husband or the mistress say anything or display any kind of reaction.

The wife continues her emotional talk: ‘I’m nine-months pregnant. I’m due in two weeks.’

‘Who the f*** are you?’ the angry wife asks again, prompting the other woman to laugh.

A few moments later the husband finally breaks his silence as he picks up his towel, saying: ‘we got a divorce.’

‘We aren’t divorced,’ the enraged mother replies. ‘What are you talking about?’ she says, before adding: ‘you were just at my house today.’

Then the wife directs her frustration toward the mistress, shouting: ‘what did you do with him? What have you done with him?’

Right before the TikTok ends, the husband walks in front of the camera, holding the dog leash.

‘You’re f****** disgusting,’ the wife shouts at him. ‘Disgusting!’
