Rankin, who gained popularity after appearing on Channel Nine's social experiment MAFS, announced she was expecting her first child with boyfriend Jax Manuel earlier this year. The 28-year-old personal trainer confirmed the news to NW, revealing she was 13 weeks pregnant and suffering from "intense" morning sickness.
She also said at the time she hopes that having a baby will save her from "being that MAFS girl" and people will realise she's a "different person" to who she was 12 months ago.
Davina rose to fame on Married At First Sight last year, when her relationship with Sydney tradesman Ryan Gallagher ended badly. She plotted an affair with another groom, Dean Wells, during the experiment and the scandal made headlines for months.
"I feel like there was never a time when I wasn't with Jax. MAFS seems like a whole other world. It's strange," she said.
Congratulations to the new parents!
