Lizzie and Seb's attraction was instant when they met at the altar and were the only couple to leave the experiment together.
Returning bride Lizzie came back for a second shot after her disastrous match with Sam Ball in the previous season who ended up cheating on her with co-star, Ines Basic.
The couple faced their fair share of challenges throughout their relationship. When the coronavirus pandemic first kicked off, the couple's plans to move in together were put on hold and the two tackled a long-distance relationship - Lizzie was isolating in her hometown of Newcastle whilst Seb was in his hometown Adelaide.
"It's definitely not easy, and we both thrive on physical touch. So that's a bit of a downer, because we can't do that right now," she told 9Entertainment in May 2020 of being apart from Seb.
Personal trainer Seb however added that their phone conversations have been the couple's "bread and butter".
"We've gotten closer, we've strengthened our bond, but we do still reach out for physical touch," he explained.
Back in September the couple fuelled engagement rumours when they exchanged rings with each other's initials inscribed on them.
"He said to me ‘Is it S & L ?‘ I said ‘Yeah, baby’ @seb.guilhaus Corny but I love it," Lizzie captioned a photo of their matching jewellery on Instagram.
Fans quickly took to the comments section and it didn't take long for some to ask if a wedding was on the cards.
"Can he put it on your left finger already 🙄 haha your story is actually the best thing ever to come out of MAFS," one fan joked,
"Best couple hope u marry too," penned another.
There are now only three remaining MAFS couples out of 60 of the experts' pairings that are still together.
Season two's Erin Bateman and Bryce Mohr who met on the 2016 season are the franchise's longest-lasting couple whilst season six saw the successful matchings of Jules Robinson and Cam Merchant as well as Martha Kalifatidis and Michael Brunelli.
In fact, Jules and Cam have made their love official and tied the knot for real in November 2019.
