The soon-to-be mother of two revealed that the pregnancy was unanticipated, with the realization occurring while they were filming the Channel Seven series.
“The news came as a huge shock to both @james_ciseau and I as we found out while we were half way through filming @brideandprejudiceau,” Tori wrote, before adding:
“It was a very welcomed shock to us with lots of high emotions at the time. We honestly can not wait to meet our new little bundle of joy in a few weeks.”
Things became heated between Tori and her mother Mary-Ann on Tuesday’s episode of Bride and Prejudice, with the posh mother storming out of an intense therapy session after an argument escalated.
Mary-Ann has been doing her best to end Tori's relationship with tradie James on the series, urging her daughter to date a well-to-do professional man instead.
But when the pair sat down with therapist Leanne Hall, Mary-Ann couldn't handle the home-truths that came up about her parenting after Tori revealed details around her childhood during the session.

Tori spoke about her younger years, claiming that Mary-Ann had never been there for her during certain traumatic events in her past.
But her mum wasn't having any of it, walking out of the session and leaving her daughter in tears.
"I don't deserve that," Mary-Ann snapped to a producer.
"I'm a mother at the end of the day. Show me the respect that I deserve."
She added: "She needs to build a bridge and get over it, because I'm done."
Bride and Prejudice airs Mondays and Tuesdays from 7:30 pm on Channel Seven.
