Lizzie and Seb were the only couple from the 2020 season of Married At First Sight to complete the experiment as a couple.
Despite being separated for months due to the coronavirus pandemic, Seb made the move from Adelaide to Sydney and was reunited with his girlfriend but after over a year of dating, the couple announced their break up in January 2021.
"We have mutually decided to end our relationship as boyfriend and girlfriend. We want to thank everyone for the endless support we have received on our platforms," Lizzie and Seb's identical Instagram captions read.
"Please be kind and respectful. We are aware you have followed parts of our journey, but please remember we are real people, and we are both navigating our way through this time to the best of our abilities.
"Naturally we are both aware there will be countless rumours and so on. Again, we are both navigating our way through this time so please be respectful and we won’t be allowing comments on this post. It is still fresh for us both, we just know there has been some curiosity as we have shared parts of our relationship online and we met on national television."
The reality stars ended their posts: "We are both respectful of each other and are still involved in each other’s lives. We both have cherished each other and have grown together. We would like to send love and well wishes to all."
Back in September 2020 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.
