It is the family-friendly show that is a world away from the romantic trials and tribulations of Married At First Sight.
But Lego Masters contestants Kaitlyn and Miller have proved that Cupid’s arrow knows no bounds in reality TV after revealing they are now a couple.
Speaking to 9Honey on Sunday, Miller spoke about how their unexpected relationship bloomed behind-the-scenes, admitting that he initially had no idea Kaitlyn was interested in him.

‘We were friends from when we first met and we’d hang out during free time in filming,’ he recalled.
‘But I was completely oblivious to Kaitlyn’s flirtations.’
Miller, who is currently channeling his Lego-building skills into a Bachelor of Industrial Design degree, said their fellow contestants did a lot of the legwork.

It was only when Lego Masters participant Cade told him that Kaitlyn was interested in him that ball started rolling on their relationship, Miller revealed.
The pair went on a few dates together as friends, before the university student made the final move over a breakfast date.
‘I leaned over the table and said, ‘Kaitlyn, I’ve got to get something out the way. I want to make sure -is this a date?’ and she said ‘I guess it is now!” Miller said.
Miller and his friend Jordan, 19, are still going strong in the highly-rated Channel Nine offering but Kaitlyn and her friend Marielle, 28, have been eliminated.
They were sent packing after disappointing Lego expert Ryan McNaught with their under the sea TV build.
‘The scale’s all out of whack – I don’t think you know what scale you’re working with,’ Ryan said before sending the design duo packing at the first opportunity.
