Sierah Swepstone and Billy Belcher were matched by the Married at First Sight (MAFS) 2025 experts.
You probably recognised Sierah from the 2021 season of The Bachelor. Sierah was a contestant of Jimmy Nicholson‘s season of The Bachelor in 2021. He wound up choosing Holly Kingston for his final rose. (The pair are now married with a baby).
Billy has no reality background but hails from the UK as a plasterer by trade and according to The Daily Mail he was brought to the reality show to bring a “dash of excitement.”
But are these two still together? Let’s find out!
MAFS’ Sierah and Billy’s pairing

According to her Channel 9 bio, Sierah is outspoken, brazen and resilient. Meanwhile, Billy calls himself Loud, confident and romantic.
Sierah came onto MAFS looking for someone kind, caring, compassionate man and a husband that she can fall in love with for the first time.
Meanwhile Billy was hoping to find a wife who’s positive, confident, and who enjoys Saturday nights at home with a glass of wine and a home-cooked meal.

Are Sierah and Billy dating outside of the experiment?
Sierah and Billy admitted that they did the deed during their MAFS honeymoon, which certainly seemed like a good sign for the couple.
Unfortunately, however, meat plate-gate proved too much for them to handle and on Episode 17 Sierah and Billy both decided to leave the experiment… sort of.
Shit hit the fan when Sierah admitted she found it easier to talk to groom Adrian Araouzou after the two shared a private dinner. The dinner revelation blindsided both Billy and Adrian’s TV wife, Awhina Rutene (even if there weren’t even any veggies).
At the following commitment ceremony, Sierah apologised to Awhina but didn’t do the same for Billy.

Billy was also called out for suggesting a “wife swap” with Adrian. Though he apologised, he made it clear he felt neglected in his relationship with Sierah, saying he got “sweet F-A” from her.
Both decided to leave, but after a heartfelt post-decision chat, Sierah regretted her choice. Tough, I guess.
Billy, however, stood firm, saying “I don’t regret my decision”.
So no, it’s safe to say the two are no longer together.
The MAFS experts offered the two some cold comfort on the night saying they shared a “breakthrough as two humans, not necessarily as a couple”. So… at least there’s that?
Married At First Sight (MAFS) 2025 airs Sundays at 7pm and Monday – Wednesday at 7:30pm on Channel 9 and 9Now.
