To date, Lizzie and Seb are the only lasting couple from the 2020 season of Married At First Sight.
Despite being separated due to the coronavirus pandemic, the couple managed to make it work.
After months apart, Seb made the move from Adelaide to Sydney to be reunited with his girlfriend and since then, the pair haven't stopped with the loved-up social media posts.
Now it seems these two are in for the long haul - and that Lizzie has finally found The One.
Seb took to Instagram to gush about Lizzie - and his post has many fans questioning whether they're about to get engaged.
"I used to believe in 'the one' .... a person would magically appear and we would effortlessly slip straight into bliss, read each other's minds, like the same things, tell the same jokes..... and that any relationship other than this was simply not to be," Seb wrote.
"Now I think that's false.... we may be so quick to dismiss partners, to move on, to run when challenged, to avoid understanding, to leave before the layers are peeled...... maybe out of fear, social pressures, past hurts, the expectation of disappointment."
He continued: "I always admired the stories of parents and grandparents .... married 50 years .... sticking together and building a connection through chaos .....wars ... poverty .... each hurdle overcome, the deeper the connection would become...."
"'The one' could be all around you ... right in front of you ... waiting for the effort to be put in ... for the trust to be built ... like anything in life you only get out what you put in ... well I believe we have put in and more and more each day we are being rewarded."
Seb's followers praised him for his thoughtful and kind words, but one key question kept popping up in the comments.
"When are you guys gonna make it official?" asked one fan.
"You proposing soon then?" another penned.
One even exclaimed: "PUT A RING ON THAT FINGER!!!!"
Lizzie also fuelled engagement rumours when she shared a close-up shot of her left hand with a nude manicure and no jewellery in sight.
"Bored. Need a new vibe," she captioned the snap.
"Where all your sparkling jewels? Maybe a new one is coming? He he he," a fan cheekily commented.
"Big diamond will fix it," penned another.
So could Lizzie and Seb follow the lead of season six couple Cam Merchant and Jules Robinson by getting legally married?
Cam and Jules, who were the golden couple of the 2019 season, officially became husband and wife in November that year in a televised special that aired on A Current Affair.
“For us, putting our wedding and the key moments of it on TV, it’s not about money or anything like that. It’s purely about the love and support we had from the public,” Jules previously told Who.
"People are invested in our relationship and we want to show that you can find love in the craziest of places."
Guess we'll have to watch this space and see if Lizzie and Seb follow suit!
