She shocked fans earlier this year when it was revealed she and husband Daniel MacPherson had welcomed a secret son together.
And while the usually private couple shy away from sharing details of their personal lives online, over the weekend the former Home And Away actress delighted fans by posting the first-ever selfie with her son Austin online.
In the new black-and-white photo, Zoe can be seen going for a walk with her bub in the carrier, with Austin rocking a koala-inspired pom-pom beanie.
In an adorable touch, Zoe and Daniel's baby holds onto his mother's arm during the outing.
"Two pom poms are better than one 🐨Morning walks with my ❤️," the 39-year-old penned alongside the sweet pic.
The rare snap also gave fans a small peek at their baby's features and it's fair to say, the seven-month-old's button nose and chubby cheeks are beyond adorable.
Proud dad Daniel, 40, was quick to comment on the photo, simply leaving a koala and love heart emoji.
While Zoe's former Home And Away co-star Sarah Roberts said: "Lil cuties!"
"Awww my heart 💙," singer and mother-of-one Natalie Imbruglia penned under the snap.
Opening up about fatherhood, Daniel said the current pandemic meant he could spend more time with his new addition.
"It doesn't matter what you believe in, whether you believe in God or the universe or Mother Nature or karma or whatever, life puts you where you're supposed to be."
"And life went 'Hey man, you're going to be right there, locked inside an apartment for X amount of months with your son and your wife. And thank you! What a gift," Daniel revealed on an episode of athlete Samantha Gash's podcast.
Zoe and Daniel met and fell in love on the set of Channel Seven drama Wild Boys in 2011.
Four years later, they secretly tied the knot in Noosa and are currently based between Australia and LA.
