A British man who lives with his two girlfriends has revealed that he is about to become a dad for the second time as the parents decide to raise their children as a ‘throuple.’

Adam has been dubbed the 'luckiest man on earth' for the unusual arrangement

The 36-year-old Adam Lyons from East London was dubbed ‘the luckiest man alive’  two years ago because of his unusual living arrangement with partners Brooke Shedd and Jane Shalakhova, teports the Daily Mail.

But for them, it’s just part of normal daily life.

Living together in Austin, Texas, the threesome already have son Dante, two, who is the biological child of Adam and Brooke, but now Jane has announced that she is pregnant with a half-sibling.

While this might sound strange, they each insist that raising children as a ‘throuple’ is the future of parenting

.

“For us, three people works because it enables us to manage daily life so much better,” Adam says.

“So many of our friends are in 'normal' two-person couple relationships with kids, jobs and all the other typical responsibilities and I see them struggling to juggle their lives. It's difficult with two people.

“But with three parents, we always have the ability for one person to look after the kids.”

When they first came out about their relationship, the parents faced a lot of criticism but after five years together, they’ve successfully refuted anyone that said they wouldn’t last.

“We’ve been going for five years now. What we have is not a fling or a phase, we're a real family with healthy, happy kids,” Adam added.

The trio – who share a super-kingsize bed – believe that the new addition to their family will only serve to make it more complete.

Pregnant mother Jane, 27, says she never really considered having children before. But, after raising Dante with Adam and Brooke, she realised that they could do it together. 

“With three parents around, it's so doable. We can still have a social life, make time for one another and share the parenting tasks so you don't end up like the typical sleep-deprived mum! 

“With two partners, there's so much help and I'll never have to leave my kids with someone I don't trust.”

Jane, who is originally from Russia with Brooke's sons Oliver and Dante. She says they boys see nothing unusual about their arrangement as it's all they know
