Susie is currently on maternity leave following the arrival of her second child and first son, Lion.
On Sunday, both Susie and her partner Todd Carney shared their exciting baby news via Instagram with identical posts.
"Lion Daryl Carney," the caption read.
"Born an Aries, March 27 2021 at 10.50am, 7 pounds 9.4 ounces, 50cm long on a perfect autumn day. A lion’s most common traits are majesty, strength, courage, justice and might. A lion stands for both gentleness and power all rolled into one. A lion in your life enables you to bring positive changes in the lives of yourself, your family and your friends.
"We love you our little Lion. You will be one of the greats."
The proud new mum, who also has a daughter from a previous relationship, has been delighting fans and followers with pics of her new baby.
In one snap posted to her Instagram Stories, Lion sleeps peacefully dressed in a onesie and blue hat.
"Lion," Susie simply captioned the new pic, tagging Lion's dad Todd in the process.
Susie rose to fame on the sixth season of MAFS when she was matched with Billy Vincent and labelled a villain for the way she treated her on-screen spouse.
She and Todd met through social media in January 2019 and went public with their romance that same year, when Susie's MAFS episodes were still airing and it was Todd who helped her “deal with the negative publicity” she received while she was on the show.
“While the show was on, it was a difficult time for Susie, but it did make us stronger, and since then everything’s been going really well,” Todd previously explained.
