Tensions reached an all-time high during Monday night's shock episode of Married At First Sight, after bride Gia Fleur got fed up with her husband Scott McCristal and stormed off, leaving him behind. 

Gia, 35, and Scott, 33, got off to a shaky start when her mother Silvana and best friend Will Thompson visited them for dinner, alongside Scott's friends Matt and Paige.

The couple sat down to dinner with their guests, when Scott was asked a bombshell question by Will - which caused tension across the table.

'Scotty, is Gia a better version of your ex?' Scott's friend Matt bluntly asked him.

A shocked Gia immediately jumped in to tell Matt that she took issue with the question - causing significant tension across the table.

'I'm sorry! Don't compare me to his ex-girlfriend... If you want to be controversial then I will give it back, because that is what I am like,' a furious Gia retorted.

She then explained why she thought she was a much better match for Scott than his former flame.

'I don't think you can compare. I would never start an OnlyFans! I will put that out there, there is no comparison, I feel like I am a wife. He's not going to find anyone like me,' Gia sniped. 

Gia was then seen complaining to producers about being asked such a blunt question to begin with.

'Like, "How do you compare to his ex? What is going on?'" Gia ranted. 

Scott was then asked if he was still in contact with his old lover, and he bluntly said that he has 'no contact with her whatsoever'.

However, after the dinner party, tensions came to a head when Gia discovered that Scott still had a photo of his ex-girlfriend on his phone - which caused her to give him a serious ultimatum.

'There was a memory photo of me and my ex which popped up, a photo from 2020. How it went down was Gia said, 'You need to delete those photos or I am out'. I told her I am not willing to delete photos from that long ago,' Scott told producers.

'I've got nothing to hide. I am not going to remove photos from my phone of an ex, when there is nothing there, I am just not going to do it.

'Gia pretty much gave me an ultimatum, said 'If you don't delete them then I am out'. She pretty much just walked out. I don't know what to do, it is s**t.'

She was seen packing her bags and leaving their apartment building in a car, as she told producers, 'He can f**k off... I am done.'

Gia's bombshell exit puts the future of her up-and-down relationship with Scott into question, coming shortly after she was recently spotted packing on the PDA with him in public. 

It comes after a drama-filled episode of MAFS on Sunday night.

Bride Bec Zacharia faced off with her nemesis Gia at the commitment ceremony, with Gia once again sharing an explosive secret about Bec's groom Danny Hewitt. 

The trio have had tensions ever since Gia claimed that Danny approached her and said Gia was more 'his type' than his wife. 

Danny denied he ever made the comments, and Bec claimed to believe him - even calling Gia a liar.  

But behind closed doors, Gia insisted that, when the cameras were off, Bec admitted that she believed Gia's story. 

Gia confronted Bec with the confession, and revealed that Bec said that she was worried she'd have to leave the show if she admitted that she believed that Danny's eye had wandered towards Gia. 

Danny chimed in, saying that he doesn't like women covered in tattoos like Gia is like Gia is – and Bec broke down in tears.
