"So... this is happening!" Bianca wrote, revealing she is currently 17 weeks along in her pregnancy. "Excited & maybe just a little nervous for all the new adventures 2022 will bring!!!"

Mark shared the baby is due in February, writing, "+1 on the way...Super excited for 2022 and adding a new member to our little gang."

The couple has been together for a little over two years.

Speaking with Yahoo Lifestyle last year, Bianca said they first bonded over being on reality TV around the same time, "Well, we sort of met first and then I messaged him one day when I was watching the show, so we were already following each other on Instagram and I just said to him, 'I can't believe you did this show!'"

She added, "It just kind of kept growing from there, it was all just a supportive reaching out to each other going, 'How's it all going for you?' The Block had already been on air, so I'd already kind of lived and breathed through the filming process and it being on air and Mark at that stage, I think MAFS must have been close to finishing [airing on TV], and I had not watched a heap of it, so it was just fascinating – first of all just to compare shows."

"I wasn't a massive MAFS watcher, however, his particular season I just had a whole group of friends who every Sunday night it became their ritual to sit down and watch it.

"So, I felt left out that I was missing out on all of this drama that everyone would talk about during the week, so I only started watching it – well, they basically forced me to start watching it towards the end."

However, she says that the person she saw on TV, is not the person she's with right now, "It's funny, the Mark I know now, is just not the one I saw on camera, like he looks totally different. It's just weird that we've both lived these different lives, kind of compared to real life."

Bianca described it as almost being a character on a show rather than it being the real Mark.

The pair attempted to keep their new romance under wraps for as long as possible before going public together.
