Rounding up their nearest and dearest friends, the couple rung in a quarter century of wedded bliss by re-marrying in an intimate ceremony at the Bathers Pavilion on Sydney's Balmoral Beach.
Their bridal party was made up of their three grown-up children, sons Jake, 24, and Louis, 22, and daughter Billie, 20.
Lisa stunned in an off-the-shoulder Pallas Couture gown while former Wallabies player Peter, 56, rocked a dapper tux.
In fact, the former magazine editor admits her beautiful dress, which she first wore to the 2015 TV WEEK Logie Awards was the inspiration behind their second wedding.
The 57-year-old the Daily Mail Australia at the time she asked her husband if her frock was too bridal to wear to the Logies.
"And he said: 'I don't know what it is but our 25th wedding anniversary is in two years, let's get married again?'"
"So in two years' time we are going to go to Vegas and get married again. I have plenty of time to prepare for another wedding. I'll wear this dress."
True to their promise, Lisa and Peter said "I do" once again but appeared to ditch the Vegas idea and instead they opted for the very fitting location of Balmoral - where they first tied the knot back in 1992.
"When 25 years passes in the blink of an eye," an elated Lisa penned on Instagram.
Lisa's co-star Sylvia also took to social media to congratulate the couple.
"So, these two love birds just got married again...in the same spot where they first said 'I do' 25 beautiful years ago," she shared.
The newly-renewed Mr and Mrs partied the night away in good company with the likes of Channel Nine stars Sylvia Jeffreys, her husband Peter Stefanovic, Ben Fordham, Georgie Gardener, Richard Wilkins, his new girlfriend Girginia Burmeister, and billionaire businesswoman Gretel Packer in attendance.
Lisa's Today co-star Karl Stefanovic was absent from the event.
Channel Nine confirmed the 43-year-old is on annual leave, explaining: "Karl didn't attend Lisa's vow renewals as he is on annual leave overseas."
Lisa and Peter were first introduced by mutual friend and 60 Minutes star Liz Hayes and they married just three months after meeting.
"It just felt right. It didn’t feel hard. It was on a Sunday night, and I said: 'I’m tired of this, will you marry me?’ And she said: ‘Yes, I will marry you,'" Peter revealed during an interview with Mia Freedman on her No Filter podcast last year.
"We don’t have 365 blissful days a year. I say we have 50 blissful days a year, 300 pretty good days and 15 shockers. But as we have got older, no joke, 15 shockers are now down to three shockers," he added of their relationship.
