Showing off some of their sweetest moments - from becoming engaged for real to announcing their pregnancy - the reality TV star gushed about her partner.
"We met and fell in love under the craziest of circumstances," she writes. "Neither of us could have ever imagined that 365 days later, we would be madly in love, matching tattoos, living together, adopted a puppy, engaged, planning our wedding and soon to celebrate the birth of our children!"
"You truly make me so happy and feel loved every single day and my life is exceptional because you’re a part of it."
Posting his own photo carousel on Instagram, Bryce shared the love for his fiancée alongside four snaps from their 'wedding' day.
"As a beautiful woman once said on September 18, 2020, 'Whatever our future holds, all I know is my new forever begins here today with you,'" he says, referencing the wedding vows they exchanged in their first encounter on Married At First Sight.
"She wasn’t wrong.. and my life is better for having you come into it. Happy anniversary, love you so much!"
At 25 weeks, Liss is past the halfway mark of her pregnancy.
Opening up about becoming a mother, the 32-year-old star said "Words cannot describe the joy, love and pure excitement we feel for one another and for our babies."
In a recent Instagram post, she admitted the twin boys are more prone to kicking as time ticks on.
"The belly has certainly popped in the last few weeks - and every now and again, our two little babes give me a subtle jab, reminding me that their time to join us is rapidly getting closer," she wrote.
Not long to go now!
