No one suspected a thing as the 25-year-old said "I do" in a secret ceremony in NSW's Blue Mountains.
Determined to keep the day just between loved ones, Jesinta played coy by working right up until the day before her wedding, where she opened the annual Christmas window display at Sydney's David Jones on Thursday.
Just last week, the former Miss Universe entrant casually threw the scent off her big day during an interview on The Today Show.
Focusing on her newly released lifestyle book, Jesinta told host Lisa Wilkinson that her wedding plans had been put on hold yet again.
"No, for us, this year for us was focusing on health and happiness and getting through the year," the model expertly explained.
The David Jones ambassador also admitted to Kyle and Jackie O that she was in no rush to become Mrs Franklin.
"We're both really young and we've had a really, really busy, big year. You know, me changing agencies and Buddy obviously making the grand final."
"For us, health and happiness were the big focus this year and the marriage was kind of put on the back-burner," she explained to the radio hosts.
It has since been revealed that in between all of Jesinta's work commitments, she was intricately planning her special day.
According to friends close to the pair, Jesinta and Buddy used the aliases "Shaz and Tony" to book everything. Guests posted their congratulations to social media and even penned the hilarious pseudonyms in their captions.
"Tony and Shaz congrats!!! Great day," one attendee wrote.
Despite it being a lavish event, sources noted it was "pulled together really quickly".
To throw people off, friends and loved ones were ordered to post various locations of the wedding, including the Barossa Valley and New Zealand's Queenstown. It was eventually confirmed that the nuptials were in fact took place at Mount Wilson's Wildenstein Gardens in the Blue Mountains in a private garden.
A guest at the intimate affair told Fairfax Media, "only their immediate friends and family, no cousins or anything" were invited.
"It wasn't a stuffy wedding. She [Jesinta] is known for being laid back and easy going and that's exactly what she was as a bride. They danced all night long and were surrounded by people who love and respect them."
The bride wore a custom made ivory and nude Vera Wang gown and cathedral veil during the ceremony, before changing into a bespoke long-sleeve lace gown for the reception.
The loved up duo's guest list included Jesinta's sister and stylist Aleysha Campbell, close friend Elliot Garnaut, make-up artist Michael Brown and Hawthorn great Jarryd Roughead.
Also, flying in to help the model and AFL great celebrate was Buddy's sister Bianca and her husband Wallabies star Matt Giteau, who jetted in from their home in France.
Dancing the night away, it's been reported that they all indulged on endless goblets of Moët & Chandon champagne.
We can't wait to see more from the day, in the coming weeks.
Until then, Jesinta and Buddy have kicked off their honeymoon.
Earlier today the 25-year-old shared a snap of a car driving down a leafy road, penning, "Let our adventure begin."
