Watch the shock moment MAFS UK’s Kieran and Kristina clash in furious argument after he told her ‘I’m wasting my time’

MARRIED At First Sight's former golden couple Kristina Goodsell and Kieran Chapman lock horns in an explosive argument tonight after he expressed fears he was "wasting" his time in their marriage.

A teaser for the next E4 episode shows the pair clashing during a double date with Sasha Jones and Ross McCarthy.

Fans were quick to call out mechanic Kieran for "making excuses" after admitting he did not want to be "intimate" with his spouse.

He also heartbreakingly admitted his fears he was "wasting time" with his wife as he appeared to embark on a huge U-Turn on their partnership.

Tuesday's Married At First Sight instalment will see things go from bad to worse for the fan-favourite duo.

They are seen hitting a crazy golf course with Sasha and Ross - who have also had their fair share of marriage woes of late.

As the show voiceover teases a "disastrous double date" Sasha, wearing a pink hat, adds: "This is the worst golfing session I've ever had in my life."

As she holds her head in her hands, Kieran can be seen gazing straight down at the table.

As the voiceover promises the "biggest upset of the experiment" Kieran can be heard telling Kristina: "You and my ex, it's actually scary how similar yous are."

The East Sussex based bride, who held Sacha's hand for support, was seen looking hugely emotional at the stark words.

As she walked away from the conversation with her hands in the air, she said in a piece to camera: "I am fuming.

"I'm not his ex."

She is then seen sobbing as she is escorted out by Sacha.

It remains to be seen if the spat will signal the end of their marriage.

TOUGH TIMES

After the couple moved into their apartment together cracks started to show - with Kieran kissing another wife in a game.

Kieran then admitted on Monday's commitment ceremony episode he did not want to be "intimate" with his bride.

Despite being hugely supportive of Kristina's battle with PMDD when she revealed her condition during their Honeymoon, the real-life implications have hit home for the groom.

In his frank remark on Monday's episode, he said: "At the last commitment ceremony, I explained how the PMDD was affecting me.

"But I've since realised that there's underlying areas where we're not similar that are important to me."

MAFS expert Mel Schilling then asked: "What made you say that?"

Turning to his wife Kristina, he said: "I asked you the other day, didn't I?

"What's more important; finding a husband or pursuing something that you're really passionate about?"

He then told Mel: "She said finding a husband and I went, 'This is why we're very different'."

Having her say, Kristina then added: "Coming in here from day one, I wanted to build a new life wherever that took me."

Meanwhile, off screen, Kieran has broken his silence after allegations he had moved on with Kristina with a co-star.

It came after he told his co-stars "the spark has gone."
