Jules Robinson has hit back with a scathing response to a critic who accused her of not spending any time with her two sons.

The former Married At First Sight star, 44, shares children Ollie, five, and Carter, one, with her husband Cameron Merchant, who she met on the reality TV show.

She has become quite the successful businesswoman and influencer since leaving the Nine series, but one follower has nevertheless taken aim at her parenting.

On Thursday, Jules shared a screenshot of a mean-spirited DM she recently received on Instagram.

A follower had responded to a story she posted of herself seemingly going out to a venue, saying: 'Do you ever do anything with your children?'

Jules posted the DM for all her followers to see, cropping out the username of the critic, and added a rolling-eye emoji over the top.

She later shared a video of herself giving a judgemental look to the camera, saying it was her response to people who criticised her life choices.

Jules later clarified the video was not a direct response to the person who criticised her parenting.

'Also, my reel that I did yesterday, that wasn't actually in response to that message from that person,' she told followers on Friday. 

'I'm not that sensitive, trust me. I've had a lot worse. It was just to reinforce my message of what I was saying. 

'How, like, you can't win, so you've just got to make your own manual and do it your own way.'

Jules is certainly no stranger to online hate, as she recently opened up about the bizarre wave of criticism she received for her Melbourne Cup dress last year. 

The Figur founder wore a pink and green striped frock by Pasduchas which ended up being a size 'too small' for her figure.

Critics left nasty comments about the reality TV star's body, with Jules telling Daily Mail in December that naysayers were acting like she was attending the Oscars.

'I didn't plan my outfit for six months. It got flown to Melbourne, I arrived in Melbourne and tried it on for the first time on the day,' she said.

'It's just a dress. It's just a day. I'm not murdering anyone, I'm not hurting anyone. Get over it. Yes, I was uncomfortable.

'It was too small and I just had to go, "You know what? F*** it. I'm going to dig deep, feel confident and have a good day."'

'It wasn't right for me but it was just a dress, it was just a day. It's just the Melbourne Cup, it's not the bloody Oscars for God's sake.'

Jules went on to joke the dress was 'the gift that keeps on giving', as she revealed Pasduchas ended up selling out of all their pre-orders following the backlash.
