Married At First Sight bride Gia goes rogue and rips into former TV husband Scott during vicious spray and makes horrible remarks about his intelligence after their split

Married At First Sight's Gia Fleur has ripped into her ex-reality TV husband Scott McCristal in a vicious spray after the pair left the experiment.

The 35-year-old mother went rogue on Thursday in a lengthy clip she shared to her social media, claiming Scott could not 'read, write or spell'.

Gia also boasted about her new boyfriend Alan, and said that once she split up with the 33-year-old businessman he 'ghosted her' because there were 'no cameras around'.

The notoriously fiery bride appeared to be responding to a radio interview Scott gave on Triple M's 92.9 Robbie and Carly Show this week.

After sarcastically referring to Scott's radio appearance as 'cute and sweet', Gia’s remarks soon took a sharp turn.

'[The] elephant in the room here...the bigger problem we need to address, which is that you [Scott] don't know how to spell, read or write.'

She then appeared to claim that Scott had mispronounced the word anonymous and had mistaken the meaning of 'epiphany'.

'An epiphany is a moment that comes to you in your brain, in a moment like a light bulb, like ''I’ve got a thought that's crazy, it's an epiphany''.

'So when you use 'epiphany' and say ''Gia, and I had a big epiphany last night, and we got through it''- you mean 'tiff'.'

She also claimed that Scott had misunderstood the phrase 'set in stone'.

'You mean "setting the tone"' she said.

Elsewhere, Gia slammed Scott for mentioning her eight-year-old daughter, who she had introduced to her TV husband during the experiment. 

'And how about we do radio interviews about getting education back on track instead of worrying about what the f*** my daughter is doing - she’s great,' she said. 

She took one final shot at Scott after he criticised Gia for quickly moving on to a new relationship after their split.

'I’m actually in love, and I’m in the best relationship I’ve been in my life, it's not just a fling or whatever,' she said.

'…And you’re not one to dictate how quickly someone can fall in love because you couldn't get there, darl.'

After the feisty bride shared the stinging video on Instagram, followers were quick to weigh in on Gia's scathing remarks about Scott.

'OMG, how rude you are,' said one shocked person, while another added: 'Acting like a 13-year-old who just got accepted into the popular group of schoolgirls.'

A third person said, 'Yuckkkkk, putting him down to make herself feel better. Bro yuck.'

Gia made headlines earlier this month when bombshell photos of her new boyfriend, Love Triangle star Alan Wallace, surfaced while her MAFS marriage was still playing out on screen.
