One little doll has driven a wedge into KC and Drew's relationship on Married At First Sight.
Drew tells TV WEEK he can't believe that bringing it with him on honeymoon has turned into such a huge deal.
"I didn't even think it would be a thing and then it became a thing and it was like, 'Oh s---," the Cairns muso says.
KC has a problem with the doll because it was given to Drew by his female housemate, Jessie.
But Drew says it was just a "spur-of-the-moment" decision to bring it with him.
"We watch Rick And Morty – it's the only TV that I really watch – and she had a Rick And Morty doll," he explains.
"I was walking out and I was very nervous and I picked it up off the table and I was like, 'Oh, can I take it with me?'
"I didn't think anything of it and it was probably one of the silliest things I've ever done."
Drew says Jessie is "awesome".
But he understands that he and KC, a dancer who's spent the past year in the US, come from very different worlds.
"She comes from LA where people were just doing horrible things," he explained.
"You had to watch your man and watch your back and watch your everything. I'm so far from that world. I just don't hang around with people who are like that."
