"💕 Congrats!! Xx" Sophie's fellow finalist Brittany Hockley penned.
Runner-up Cass Wood also commented with: "SO HAPPY FOR YOU GUYS!!! 😍❤️❤️❤️"
Sophie and her fiancé went public with their romance in March 2019, just months after Nick 'Honey Badger' Cummins famously chose neither Sophie nor Brittany in the 2018 finale - a decision that the rugby player stood by.
"I just know in my heart, I've done the right thing. They are two amazing women who are walking out of my life right now. It wouldn't be fair to enter into something and a few months later, break her heart," he said on the show.
Sophie shared an emotional statement following the finale and though she struggled with the aftermath, admitted she had no regrets.
"There is no denying that this isn’t the way I hoped my journey would end. I unknowingly reached a point in time where not only could I see a future with Nick, I really wanted it," she wrote in 2018 on Instagram.
"But in saying that, I am a firm believer that things happen for a reason, and now was not my time. I’m slowly coming to terms with this.. and it’s okay 😌 Do I have any regrets? Absolutely not. You guys were only shown such a small part of a very, very long journey.
She added: "It was nothing short of an emotional roller coaster. But, overall what an amazing experience I have just been through. The friendships I have made, the personal growth I have experienced - it’s priceless."
She may not have found romantic love on the dating show, but Sophie later described fellow finalist Brittany as her "soulmate."
"I found a soulmate in our friendship✨ @brittany_hockley I can’t begin to explain just how much I appreciate you," she penned on Instagram shortly after the finale.
"Thank you for being the ultimate support, and thank you to everyone else out there that has sent us the most beautiful messages. We see them all! YOU ARE ABSOLUTE GEMS! Now it’s time to head into that next chapter 📕 #BringItOn"
Whilst Sophie has a ring on it, her Bachie ex Nick is rumoured to be currently dating Sydney socialite Alexandra George.
