She welcomed her first child, a son named Oliver Chase, with her husband Cameron Merchant in October last year.

And on Thursday, Married At First Sight’s Jules Robinson celebrated one of her son’s first milestones as he saw a rainbow for the first time.

The 38-year-old shared a video to Instagram of herself singing I Can Sing a Rainbow  by Peggy Lee to her son as she held him in her arms.

‘Red and yellow and pink and green. Purple and orange and blue I can sing a rainbow sing a rainbow, sing a rainbow,’ she sung.

Jules captioned the post: ‘Excuse the voice, excuse the mess. Who cares. My little man saw a rainbow for the first time today #simplethings #rainbow.’

It comes after Jules and her husband Cameron took their son Ollie on a trip to the aquarium.

Former cricketer Cam shared adorable footage of baby Ollie marvelling over sea life during a visit to the Sydney Aquarium.

Ollie smiled and giggled in his pram as fish, stingrays and even a shark swam above him in the large tank.

At one point, Jules appeared emotional as she held Ollie in her arms to get a closer look.

While little Ollie loved the aquarium, he wasn’t so impressed with his parents’ singing abilities.

Cameron posted a funny picture of Ollie after they sang Baby Shark with the rest of the parents at the aquarium.

Cameron and Jules are the most successful couple the controversial reality show has ever had.
