The pair first started dating in 2017 soon after Franich's stint as The Bachelor and he proposed in March this year.
The pair told Woman's Day their plan now is to move into a new place together and start a family.
They're on the hunt for a family home after moving in to an apartment together last year, and now, Franich says: "We do want kids in the next 12 months".
For Simpson, it’s perfect timing having the wedding stress done and dusted. She says: “I just want to be relaxed. It’s ok to rush around for a wedding and pack in all these hours, but it’s not ok when you’re pregnant. I don’t want to be in that type of framework when a baby comes along – I want to be real chill.”
