Both Sam and Jordie took to Instagram in September to share the baby news - posting identical images on their account. Not long afterwards, the couple shared they were expected a boy.
"There is a tiny human coming soon…everyone act surprised when he inevitably inherits his parent's odd sense of humour," Sam began her caption.
"We don't take ourselves or life too seriously, and we're hoping to teach our tiny one the same values we share… the importance of being unapologetically yourself, always finding the fun and humour in all the small things, and that being kind, loving and empathetic is a superpower."
"Thank you to all our beautiful friends and family who have supported us during this time, you're all excellent secret keepers."
