The couple rose to fame on The Block’s eighth season in 2014, which was dubbed Fans v Faves.
Announcing the happy news to Instagram, the couple shared an adorable snap of the two of them lying on the sand, along with their son Ziya, with a drawing of a fourth person.
The duo captioned the adorable snap: 'Our little family is about to get a little bigger! Ziya is totally pumped to have a little bro or sis - due to arrive May 2018. I guess everyone will start telling us ‘you thought you were busy with one kid’ 😂 Bring it on little one, we can’t wait to meet you! #WithChild #YesTheresOnlyOne#BunInTheOven #KyalandKara'
The happy couple have been married for nine years, and have now launched a career in renovations, currently working together on Diverse Construct.
Their first son Ziya was born just over a year ago.
Congratulations to the happy couple!
