Actress Bianca King is also expecting.
Bianca revealed the news herself via social media posts.
Her announcement came just a few days after her sister-in-law, Iza Calzado, revealed that she was also pregnant.
Iza's husband Ben Wintle is the brother of Bianca's partner, Ralph Wintle.
"I lived my life exactly the way I wanted. Took my time and did everything I needed to do. When it was time for us chase the dream of becoming parents, we were ready as ever," the 37-year-old star wrote on Instagram.
According to her, it was a "long journey," relating how it was not easy - being in their mid-late 30s.
"I mentally gave up and was about to do IVF. But surprise! A natural miracle happened," she said.
"I thank my beautiful husband for setting me on the path to becoming a mama. Ralph is already the best dog dad, being so hands-on with Willow. We both feel confident that we will be the best parents," she said
Bianca hopes that their baby will inherit Ralph's looks and athleticism, but her personality and creativity. Then their shared wit and wisdom.
Last year, Bianca and Ralph tied the knot in Sydney, Australia.
