The Married At First Sight UK cast reunited for an explosive reunion episode on Monday, leading to tears, tantrums and turmoil. 

Yet one face was notably absent from the episode, with Polly Sellman failing to show up after her romance with ex-husband Adam Nightingale came to an explosive end during the final dinner party. 

After fans questioned why Polly, 28, failed to film the reunion show, she took to TikTok to address their concerns. 

Having filmed herself lip-syncing Alessia Cara’s hit track, Here, she captioned the post: ‘Seems fitting for everyone who’s asking me why I didn’t attend tonight.

‘I was also in Centre Parcs when filming was, and I pulled out 2 days before because it wasn’t the best decision for me at the time.

‘I wanted to stay with my best friends who genuinely cared about the head space I was in at the time.’

MAFS UK star Polly Sellman has revealed the real reason she pulled out of the explosive reunion with two days notice after fans questioned where she was in Monday’s show

Polly wasn’t the only star addressing the explosive reunion, with Lacey Martin breaking her silence this week after ex Nathan Campbell accused her of plotting a ‘showmance’.

Despite ending the experiment with a bright future ahead last year, the couple split just weeks later, after Nathan claimed Lacey said they were ‘better off as friends.’

In toe-curling scenes, Nathan also shared that Lacey suggested they keep up the ruse of their relationship to ‘get magazine deals,’ while she hit back that he blocked her on social media.

While Nathan attempted to confront Lacey about her behaviour, she insisted she didn’t want to go ‘тιт for tat,’ instead reading a letter looking back at their relationship, before clashing with him yet again at the dinner table.

In another awkward moment, Lacey dramatically declared she was ‘leaving’ as both Nathan and pal Kieran Chapman continued to press her on the ‘showmance’ claims.

However, many of the guests hesitated before going after her, with Ella Morgan seen asking: ‘Is anyone going to go after her?’ before several girls convinced her to return.

Taking to Instagram Stories to share a post, which she has since deleted, Lacey claimed that much of Nathan’s true colours were ‘edited out,’ saying that he ‘refused to wish her luck for Race For Life.’

She wrote: ‘Thank you to every single person who has messaged me! I’m overwhelmed with how many people can relate.’

She continued: ‘I love you all and forever grateful. So sooooo much was edited out! What about Nathan not withing me good luck for race for life? As my Mum had cancer.

‘What about Nathan agreeing saying he wanted to do a boy band and modelling and deals???

‘I stuck up for myself. But everything has been edited out! Due to Nathan’s mental health! What about mine?

‘Sending everyone love sending me beautiful messages from start to finish, be mindful.’

And while the reunion implied that many of the couples were reluctant to follow Lacey when she stormed out, fellow bride Sacha Jones has taken to Instagram Stories to share the truth.

A post, which Lacey has since re-shared, said: ‘Just for the record @lacemartin_ said she needed to leave for her mental health. And we all told her to stay but she insisted on leaving.

‘That’s why no one went after her. And I did say I’m not convincing someone to stay if it’s not healthy for them to. 

‘She knows I was there for her. Including telling Kieran not to gang up on Lace when it’s nothing to do with him. I love both Nath and Lace.’

Lacey went onto share a string of positive comments from fans on Facebook, before thanking her fans for their ‘kind messages.’

Following their split, the pair’s confrontation ended in tears with Lacey denying she told Nathan they should continue their relationship to boost their fame

Despite being one of the only couples to make it through the entire experiment – last November it was reported that they had secretly split.

The 24-year-old engineer from Somerset and Hertfordshire-based office manager, 27 were lucky enough to have a union on the show that was relatively plain sailing compared to some of their co-stars.

At the explosive dinner party during the reunion, Nathan admitted to the boys that Lacey told him they should continue their romance for fame and ‘magazine deals’.

Teary-eyed he said: ‘I was so gutted when it ended, I thought our marriage was going to last forever.’

Telling her side of the story however, Lacey said: ‘People are going to be shocked that it was Nathan that blocked me, I just feel that he gave up.

‘Him just blocking me like I’m nothing hurt me, I just tried so hard.’

Chatting to his co-star Kieran, Nathan went on to explain: ‘After the experiment she was completely different.

‘I was going to see her every weekend, she never came to see me once in the whole relationship, never. She said ‘I think it’s best we be friends’, she ripped my heart out.’

‘She just decided it was better to be mates, it was a bit one-sided. It goes into something that’s not genuine.’

He then added: ‘Shortly after she messaged me and said after a year you get magazine deals and things like that, showmance.

‘She sent me a text message saying the relationship she wanted would be a pretend one so she could get more opportunity from it and make more money but I didn’t want to do it.

‘It’s a bit embarrᴀssing, I don’t really want to talk about it to be honest.’

His pals were shocked as he shared the news with them. 

Last November The Sun reported that the duo secretly called it quits after filming ended.

A source told the publication at the time: ‘Nathan and Lacey really tried to make their relationship work in the real world but it just fizzled after a while.

‘The final vows were filmed in February and they were still going strong in April when the reunion was sH๏τ, but since then they have called in quits.

‘They were both sad it didn’t work out, but sadly it wasn’t meant to be.’
