Elyse Knowles has welcomed her third child with her fiancé Josh Barker, a baby girl named Java.

The Block star announced the exciting news on Instagram on Wednesday alongside an adorable video of her newborn daughter with her two sons.

'The boys with their baby sister Java. 5~12~24,' she wrote.

Her post was inundated with messages from her friends and fans congratulating the growing family on the exciting news.

'Lovely news .. Congratulations to you all, she's beautiful!' one person wrote.

'Congratulations guys! This video is just beautiful - their little smiling faces. What a fab early Christmas present,' another said.

'Oh my heart!!! How lucky she is to have two big bros. Congrats beautiful,' a third commented.

'Congratulations to all a healthy baby girl,' another said.

'I've been waiting in anticipation to see the update.. Congratulations and welcome gorgeous little Java,' one person wrote.

Elyse and Josh, who share Sunny, three, and Zali, one, revealed they were expecting for the third time in June.

Elyse displayed her growing baby bump in a series of bikini photos with her two sons during a family holiday in Fiji.

'Omg Wowowow. You do it so effortlessly!' MAFS star Martha Kalifatidis commented.

Another follower wrote: 'Such a beautiful growing tribe you are!!! Happy for you guys.'

'I cannot wait for another little human to join the fammmmm,' one fan mentioned.

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, they 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, Sunny.

'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,' she 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.
