The Daily Telegraph reports that while Monk and her parents are on speaking terms, the relationship between them is still "significantly strained". Sophie and sister Lucy had "partly repaired" their relationship, but not enough for Lucy to score an invite to the wedding.
Speaking to news.com.au in July last year, Monk appeared to subtly tease her plans for a guest-free wedding, saying she wanted "no drama" on the big day.
"I think we're just going to keep it quiet, low-key, and no drama for anyone. I just want it to be an amazing day between us," she said.
In an exclusive interview about the wedding with Stellar last month, Sophie insisted the decision to keep things intimate was a no-brainer.
"We always thought we'd elope.
"So many people said to me, 'I didn't even see my husband on the night; if I had my wedding over, we'd just elope'. So we thought, well, why don't we just get married at home? I've seen people get really stressed about their wedding and ours has been so stress-free."
Instead, the loved-up couple held an intimate at-home dinner with just two guests: Sophie and Josh. No family or friends were present.
"I'm 42, so I feel like (our loved ones) are like, OK, do it your way. We figured if we don't invite one person, then no-one could get upset," she told Stellar.
Monk and Gross met on a flight from Europe to Australia in August 2018, sharing a mid-air kiss after enjoying "three champagnes" in business class.
Before that, Bardot and Bachelorette star Sophie was known for being unlucky in love: had been engaged twice before, to French businessman Jimmy Esebag in 2011 and Benji Madden in 2007.
