EXCLUSIVE: Married At First Sight UK’s Arthur Poremba is seen passionately kissing a mystery woman at London nightclub – confirming his marriage to Laura Vaughan ends in heartbreak

Married At First Sight British contestant Arthur Poremba was seen passionately kissing another woman at a London nightclub – confirming his marriage to Laura Vaughan ends in heartbreak.

The tennis coach partied until the early hours at Libertine on Saturday with his E4 co-stars, including Rosaline Darlington, Luke Worley, Tasha Jay and Georges Bert, as the cast reunited to celebrate his 35th birthday.

And Arthur, whose wife Laura wasn’t part of the festivities, let it be known that he was the birthday boy, flirting with fans of the show and kissing a fellow partygoer in the middle of the dance floor.

An onlooker revealed to MailOnline that Arthur and the mystery brunette ‘spent the whole night together’ after she joined Arthur at Kabo restaurant before continuing the fun at Libertine.

Their contact confirms that Arthur’s relationship with Laura has ended. Arthur was left heartbroken after Laura rejected him during their vow renewal, despite wanting to go through with their marriage.

A source told MailOnline: ‘Arthur spent the whole night with a gorgeous looking brunette and they couldn’t keep their hands off each other.

‘They were kissing all over the club and they absolutely didn’t care who saw them, even though Married At First Sight viewers will still think he’s in a relationship with Laura.

‘Arthur was devastated when his marriage ended. He always felt like he wasn’t good enough for Laura, and when she walked out on him at their vow renewal, that emotion intensified.

“He’s just having a good time now, and it was his birthday, so a little attention wasn’t unwelcome.”

Arthur and Laura’s marriage got off to a rocky start after he admitted he had Googled his vows instead of writing them himself.

Laura and her close friends were offended that Arthur seemingly couldn’t be bothered to think about what he wanted to say at the altar and challenged him about his intentions.

The couple weren’t the perfect match, with Laura admitting her ‘usual type’ was a Chelsea boy, and that she prefers to spend her time in luxury locations in West London.

Laura’s taste in men made some of her castmates wonder if she was a gold digger, but the divorcee dismissed the accusation, saying she had always taken care of herself.

Over time, the couple bonded over Arthur’s career and motivation to succeed after he moved from Poland to Britain and established himself as a tennis coach.

Laura signed up for the E4 experiment after divorcing her first husband and described their short marriage as a tragedy of the Covid-19 pandemic.

Speaking to MailOnline at the start of the series, Laura said: ‘I’ve been married before so I know what it’s like to be married and what it means to be in that love bubble.

‘I didn’t get much of a chance to live like that during my last marriage, so for me it was very much a case of the second time being a charm, but I don’t trust myself to make romantic decisions so I’m outsourcing them to someone now otherwise, hopefully for a better success rate.”

Laura, who also appeared on Celebs Go Dating, added: ‘The wedding day was very triggering, it evoked an emotional response, shall we say.

‘I was back in the dress and my other half looked like my ex from behind and was wearing the same suit, had the same hair colour, it was all very shocking.

‘There was a moment when I thought I should run the other way. There was an extra amount of expectation and anticipation because I had done it before.”
