'The boys are excited for another brother or sister,' she captioned her post.

The couple's reveal comes one year and just a few days after Elyse gave birth to their second child, son Zaii.

In January 2023, she announced that she was expecting the soon to be middle child, explaining she was 'halfway' through her pregnancy, and that Sunny, three, was excited to become a big brother.

Josh and Elyse, who rose to fame when they were crowned winners of The Block in 2017, welcomed Sunny in February 2021.

They announced the birth of their first child shortly after revealing they had secretly become engaged.

The former reality stars moved from Melbourne to Byron Bay in 2019 seeking a quieter life.

In May 2020 purchased a $2.3million beach house in the New South Wales coastal town, which they renovated.

Elyse revealed to Stellar magazine that she was crippled by anxiety following the birth of her son.

'I got quite anxious leaving home for the first time. My heart was racing. I didn't know if I could do it,' she told the publication.

'Having [Sunny], having our dogs and getting out there... And Sunny was screaming in the car and it made me quite scared.'

'I found it hard to breathe and I had to tell myself, "It's fine, what could go wrong? Everyone has babies... you just have to go for it," Elyse added.

'It took a couple of times to feel confident. But I'm not going to lie, it was hard at the start.'

She also told Body+Soul Magazine that she and Josh avoid using mobile phones around Sunny.

'I don't want him picking it up. I don't want him playing on it at all,' the media personality said.

Josh and Elyse have been together for nine years, and engaged for two, but are yet to marry.
