The pair - who met when Constance's previous marriage was breaking down last year - reportedly wed in Karriview Lodge, Cowaramup, according to Perth Now.
Despite the fact that guests were alleged to have been forbidden to take photos of the special day, the 34 year old graciously shared one image from the day with her 268,000 Instagram followers and 1.1 million Facebook fans.
With the pair posing in festival attire, Constance captioned the Insta pic:
'From the bottom of my heart. I've never been this happy in my life'.
On Facebook, the soon to be mum of five continued:
'Tomorrow I marry this guy,' she wrote in a post late on Friday night.
'I've eaten a whole jar of Cadbury Almonds for the nerves.
'Of course the wedding almost didn't happen, for the first time we fought all week,' she added.
'A combination of stress and me pushing him to be more of a talker when he just wants a moment to think and him possibly having a realisation that he's about to marry a pregnant chick with four small kids who blogs and writes books about every detail of her relationship to the world.'
Constance added: 'I'm not your typical trophy wife. And I'm not for everyone, but hey neither is he.'
Constance and Denim first started dating while Constance was embroiled in a messy separation from her former husband of six years, Bill Mahon, with which the blogger shares four children.
Denim also has two children from a previous relationship and the pair are expecting their first child together later this year.
