And late last year the couple both shared separate pictures of themselves individually enjoying high tea at the same restaurant.
Elizabeth and Seb filmed their 'wedding' in Sydney in October, around seven weeks into production for the current season of the show and it is expected they will make their onscreen debut in two weeks’ time.
The news comes after fans once again expressed concern over Lizzie’s dramatic weight loss.
The 28-year-old reality-TV star posted a photo of herself enjoying a cup of tea, when fans took to social media to express their concerns.
"You so thin!" another added.
"Are you well? another asked.
However Elizabeth maintains that her drastic weight loss is the result of illness not dieting.
Speaking previously to an Australian magazine, the MAFS star said she had lost weight because of an auto-immune condition similar to lupus.
This means Lizzie needs to follow a strict eating plan and adheres to a high-carbohydrate diet.
