MAFS groom Chris Nield puts on a brave face as he's seen for first time since bride Brook Crompton's shock  pregnancy news

Chris Nield has been spotted for the first time since his on-screen romance imploded in a spectacular fashion. 

The Married At First Sight groom split up with his TV bride Brook Crompton during Tuesday's episode - only for it to be revealed that Brook has become engaged to her ex and fallen pregnant since leaving the show last year. 

The 31-year-old Australian footballer and construction supervisor put on a brave face at Sydney Airport before popping out for some shopping. 

Chris showed off his biceps in a black tank top which he paired with matching shorts. 

He added a pair of white socks and cream sneakers, while wheeling along a small carry-on suitcase. 

After leaving the airport, Chris got some retail therapy, picking up leisurewear from clothing store Venroy.   

It comes after Chris spoke out after it was confirmed Brook is back with her ex-boyfriend – just days after Daily Mail broke the bombshell story.

Chris, who was paired with Brook during filming, sat down for an unfiltered chat as he attempted to make sense of the twist that has left viewers stunned and cast members vindicated.

While Chris insists he has 'no ill wishes' towards Brook, he admits the signs were there from the very beginning.

The relationship scandal erupted last week when Daily Mail revealed Brook had quietly reconnected with her ex, Harry, with footage obtained by Daily Mail showing the pair kissing and cuddling while decorating a Christmas tree in October, just weeks after her on-screen marriage to Chris imploded off-camera.

It was the moment that confirmed what many on set had allegedly been whispering all along – and now Chris is making it clear he believes Brook was never fully available.

'I just don't think she was in the right place for a new relationship to form,' Chris said back in November.

'Obviously finding out during the show that she'd slept with her ex two days before we actually got married… looking at it now, I'm just feeling like if she was doing that, she wasn't ready.'

Chris said the fallout made more sense once he saw Brook had moved back into her old life soon after filming wrapped.

'She posted some sort of TikTok… three, four weeks after we finished, she's back with him living in his apartment,' he claimed.

Chris also addressed the uncomfortable reality that their connection, while strong at times, was constantly under pressure – and repeatedly threatened by Brook's desire to leave.

The groom claimed Brook 'packed her bags and threatened to walk out multiple times' during filming, saying the intense production environment pushed them both to the brink.

'We were both very particular people. And I think the environment just got to us multiple times,' he said.

'If one of us felt sh*t, the other one would jump on board and feel sh*t as well. So like she obviously left the first weekend… little things, but everything just compiled and made her sort of just wanna get outta there and get back home.'

Chris described the wedding as 'awesome' and said he was initially attracted to Brook – but the mood shifted almost immediately after a mate allegedly made a comment about her height as she walked down the aisle.

He claimed Brook was 'taken aback' by the 'footy dynamics', and said he didn't realise how much it had affected her until later.

'She told me it wasn't until… day two or three [of the honeymoon] that she changed her opinion and realised that we actually connected really well on a personality level,' he said.

But he now believes Brook's unresolved feelings – and her pull toward the familiar – doomed them from the start.

'She was going back to something familiar because she was worried about this new experience,' he claimed. 

Chris also revealed he has not spoken to Brook since a final Channel Nine media day, claiming she made the decision to cut ties afterwards.

'I knew she'd already made a decision not to speak to me after that,' he said.

Now that Brook is back with her ex, Chris believes her new relationship has made any contact impossible.

'I think it's more for the respect out of her relationship that she's in now,' he said.

'It'd be strange to let that relationship or friendship be there.'
