When we're not worrying about how much partner swapping is going to happen on this year's series of Married At First Sight, or just how many of the couples in the latest season will actually defy the zero per cent success rate and make their romance go the distance, there's another burning question we have about MAFS.
Is this show even legal in Australia?
Each bride and groom's big day has all the trimmings of a real wedding - the frou-frou dress, a celebrant (who may or may not be an actor), the bridal parties, the father walking the bride down the aisle, the cringe-worthy best man speeches, the drunken tears - but are they legally binding?
Ultimately, it's all for the cameras and the Married At First Sight weddings are not real, but rather a commitment ceremony and a promise to ride out the social experiment with honesty and effort.
"They are not," a Nine spokesperson confirmed to Now to Love, when asked if the MAFS weddings were real.
When the first season of Married At First Sight aired in 2015, the social experiment drew criticism for being "morally unsound" and an insult to the same-sex marriage campaign.
A change.org petition to have the show axed garnered 15, 000 signatures.
At the time, a network rep explained exactly how the weddings worked and revealed: "In order to comply with the Australian Marriage Act (1961) which requires one month and one day notification, a marriage in law was not conducted."
"Each participant embarked on a commitment ceremony with a wedding celebrant with all due intention to commit fully to this union for the duration of the experiment," the rep added.
"At the end of the experiment, they are given the option to continue with the relationship or go their separate ways."
Zoe Hendrix and Alex Garner from season one of were the last-standing poster couple of the show and before their sad split, they were even thinking about a real wedding.
"It's weird, we feel like we are really married anyway," Zoe, who shares daughter Harper with her ex-partner Alex, revealed to the Daily Telegraph, before they parted ways in April 2018.
"We will probably have a wedding down the track, but it's like we are already married."
Of course there's one couple who have made things official after meeting on the show: Cam Merchant and Jules Robinson.
As the golden couple of MAFS 2019, they hit it off straight away and ended the season finale with a MAFS first - an actual proposal.
Cam and Jules tied the knot in Sydney in November 2019 surrounded by family and friends, including former co-stars Heidi Latcham, Nic Jovanovic and Cyrell Paule.
Maybe true love can prevail after reality TV!

But when asked at the 2019 ARIA Awards if they'll be coming back for a cameo, the newlyweds shut down the rumours, saying "absolutely not."
"I think we'll just be flying or flag for everyone on the show hopefully finding love and that's a beautiful thing, plus a bit of drama, everybody loves a bit of that as well," Cam added.
Well there you have it. Now, start taking bets on how many 2020 couples will actually survive the MAFS curse.
