Self-proclaimed "world's most identical twins", Anna and Lucy DeCinque have taken being joined at the hip to a new level, from sharing all 46 chromosomes to splitting the attention of their shared fiancé Ben Byrne, the two Australian sisters are now attempting to get pregnant concurrently.

The 35-year-olds have starred on TLC’s Extreme Sisters, with the inseparable siblings recording their fertility journeys while on the show. The pair have undergone the same cosmetic procedures, dress alike, and even measure their food so they consume the same portions. “We just feel like we’re one person,” they explained.

Double trouble: Twins try for joint pregnancy

Having recently decided to try for babies, their motherhood goals are yet to be achieved, with the pair experiencing difficulties in falling pregnant.

In preparation for parental responsibilities, Anna and Lucy have been channeling their maternal instincts via the deployment of baby dolls, taking them out in public, and even dressing them identically, such is their kinship.

Revealing how their respective jaunts into pregnancy are yet to bear fruit on the latest instalment of the show, the pair said: "We've had some trouble trying to get pregnant, so this [using dolls] is the next best thing.”

The twins had initially made clear their desire to get pregnant at the same time back in 2021, stating: "We've never taken a pregnancy test before. It really is magical how a stick can confirm you are pregnant."

Sharing is caring

Talking about their relationship with Ben, they said that sharing a boyfriend allows them to always stay together, since dating separately led to partners who wanted to keep them apart. They first met Ben—who is also a twin—on Facebook.

He became the first man they both dated after he responded respectfully when they suggested the unconventional arrangement, they told Business Insider.

The two women have been engulfed in a relationship with Ben since 2012, although due to laws prohibiting polyamorous marriages in their native Australia, the throuple have been unable to unite in wedlock.

The sisters describe their relationship as free of jealousy, explaining that if Ben kisses one, he immediately kisses the other. Their openness has earned them more than 134,000 Instagram followers, although not everyone approves. “People just need to accept it,” they told Insider. “We’re not hurting anyone. Love is love, that’s always been our message.”

To mark their 35th birthday, the twins posted photos of themselves in matching red dresses, writing captions like “Birthday celebrations with our man” and “Together we rock.”

While they wait to fall pregnant, Ben certainly has his work cut out to sow his paternal seed in a timely and synchronised fashion.

Anna and Lucy DeCinque - dubbed the 'world's most identical twins' - are even trying to get pregnant at the same time, with the same man.

The Australian twins, 37, found fame for their commitment to remaining as identical as possible into adulthood, even wearing the same outfits and getting matching breast augmentations to maintain looking the same.

Anna and Lucy also made headlines for sharing the same fiancé, 40-year-old Ben Byrne, with whom the pair are planning to start a family.

Both sisters have made it their mission to get pregnant by Ben at the same tim, so that their respective offspring can be the same age as one another too.

Anna and Lucy have been getting some practice in for motherhood by dressing up identical baby dolls and taking them to cafes and restaurants, per the Daily Mail.

The pair's dream has always been to start families of their own at the same time later in life, but admitted that they were finding it hard to conceive.

They revealed on season two of the TLC series Extreme Sisters that they turned to the dolls to fill the void until they have real babies, explaining: "We've had some trouble trying to get pregnant, so this is the next best thing."

Anna and Lucy added: "Our dream is to be pregnant together at the same time."

The twins and Ben began to explore their journey to motherhood in 2021 when they were 35 and were thrilled to discover they were ovulating at the same time.

"We learned from the internet that when your temperature goes up you're ovulating," Lucy said, before the pair both measured identical temperatures of 36.8C, exclaiming: "We're the three degrees up. We are ovulating, we are exactly the same."

Their identical temperatures came as little surprise as the twins say they've always been "in sync with everything".

The clip from the show then sees the girls call Ben into the bedroom before it cuts to them laying with their legs up on the wall by the headboard, with crumpled sheets scattered around them as they attempt to ensure successful fertilization.

Ben added: "It's definitely going to be a challenge getting them both pregnant at the same time. It's definitely a lot of pressure, you know, the one guy. It's a matter of multitasking I guess!"

The girls are then seen tucking into a plate of pineapple pieces - after checking the morsels they eat are absolutely identical sizes of course.

They previously revealed that there is nothing they will not do together, as Anna told the New York Post: "When she goes to the toilet, I come with her; when she has a shower, I come with her.

"You name it and we do it. We're never apart. I don't think we'd function without each other. We have separation anxiety. We're bound to each other."

Anna and Lucy DeCinque are sisters from Perth, Australia. But they aren't like most sisters. They're identical twins, for starters - and their similarities go far beyond their looks. They dress the same, act the same, and, despite being 33 years old, they still share a bed.

Even more bizarre than that, though: they also share a boyfriend.

Ben Byrne, who is 35 years old, is dating both Anna and Lucy - and all three of them are very happy with the setup. "Love is love; we are all adults," they said.

But things might get a bit complicated between them in the very near future, as the two women both want to have a baby with Ben... at the same time.

The twins revealed their plans to become mothers simultaneously on Australia’s Today show.

"We want to experience pregnancy together. We want our bodies to look the same because we're so close, we always want to be together and do the same," they said.

"That's why we share a boyfriend and so we want to experience pregnancy together, it's such a beautiful thing for any mother to go through.

"We're going to make that happen. If it happens, it happens so we will see. Time will tell."

But they understand that their wishes may be hard to fulfil.

"We need to be pregnant at the same time," they said. "It’s going to be another challenge. There’s a lot of pressure on Ben."

The sisters considered going through IVF in order to have a better chance at guaranteeing that they would be pregnant, but their mother convinced them to try and conceive naturally. They have accepted, however, that the chance of them both conceiving and having their babies at exactly the same time are very low.

"At the end of the day, that's not really a call we can make. And that's when nature comes in I think. You can't control these things," they said to one another. "But it would be amazing if we got pregnant at the same time. Even if my kid was born in the same week as yours."

The twins also revealed that they both want to marry Ben. Of course, it isn't currently legal in Australia for one person to marry two different people, so Ben would be committing a crime if he attempted to do this.

"If we can change the government we would love to marry Ben," they said in unison. "I think we should marry the same man. This is what works for us. People need to get that. We aren’t hurting us."

Anna and Lucy know their lifestyle isn't exactly 'the norm', but they had some strong words for critics who disagreed with their way of life.

"We know there's a lot of people out there thinking "what the f***" but at the end of the day, it's our bodies, it's our life," they said.

"You've just got to respect our choices. We want to have babies with the same man and we want to get married with the same man. That's the way we want to live our life. We're so happy that we found a guy that we love and he just cherishes us and loves us for who we are.

"This relationship is beautiful. Ben has spoken to us about kids and he's so good with kids. We think he'll be an amazing father."

If they do eventually fulfill their wish of both having children with ben, their kids would be biological siblings, but legally half-siblings and cousins.

Eyebrow-raising identical twins, Anna and Lucy DeCinque, have done absolutely everything together their entire lives and shared far more than just their clothes.

The inseparable sisters shower and use the toilet at the same time, which could have been an obstacle when it comes to dating, as it is hard to get more intimate than that. However, thankfully, or alarmingly, they have found a man who loves them equally.

The twins share a fiancée and prefer not to have time alone with him

The DeCinque sisters are so in sync that they claim to feel no jealousy at all when it is the other sister’s turn to receive affection. The pair even remain in the same bed when the other sister and their shared boyfriend are being intimate, which understandably has been the source of a lot of questions and backlash.

Anna and Lucy have answered this question, often in sync, many times in the past, as their intensely close relationship has sparked a morbid curiosity in their sex life.

In a recent appearance on the chat show Hughesy, We Have a Problem, the sisters were quizzed over whether they share a bed while the other is having sex, and they responded, at the same time: "Yes, and that's it, that's all we're saying, we're never apart."

The pair’s partner of ten years, Ben, is fascinatingly a twin himself, but unlike his polygamist twin, his brother only has one partner.

While the DeCinques claim to feel no envy over the other sister spending their time with their shared fiancé, Ben has a well-thought-out system to keep them both happy.

Explaining how this works, the twins said, "There's no jealousy in the relationship.

"If Ben will kiss Anna, he'll kiss Lucy." Also, the sisters seem to be more concerned about not missing out on time with each other, rather than their fiancé.

The twins have gone to ludicrous lengths to ensure that they remain identical in every way. They measure out their food and drink, and even have matching fillers and cosmetic surgeries to keep their faces looking the exact same.

The trio are preparing to face challenges to their relationship

The next step, which could prove a bit of a challenge, is figuring out how to become “pregnant at the same time” so that they can experience motherhood together and raise their children like siblings.

Although they have said they are open to IVF for a higher chance of it being possible, the twins have also been exploring the natural way. “There’s a lot of pressure on Ben,” the pair admitted.

Another huge hurdle they are having to face is getting legally married, as polygamy has been outlawed in Australia since 1961.

In an episode of the TLC reality show Extreme Sisters, Anna and Lucy said: “We would like to marry him one day, but the law in Australia says we can’t, so what do we do?”

“If we can change the law and the government, we’d love to marry Ben.

“I mean, love is love; we’re all adults—we should marry the same man.”

The stars of the new TLC show Extreme Sisters certainly take the words "extreme" and "sisters" to new heights.

Australian identical twins and YouTube influencers Anna and Lucy DeCinque, 35, not only look the same, but also share the same boyfriend and bed.

The new show follows several siblings whose super close bonds defy standard sisterly behavior. In fact, in an interview with the New York Post, Lucy said: "We think of each other as one person. We can never be apart."

Premiering April 25, Anna and Lucy are just two of the several sibling pairs who will be followed around in locations ranging from Australia to Oklahoma.

Not only do the sisters dress in identical outfits, the pair - who are "always together" - are hopeful that one day they’ll marry their shared boyfriend, Ben, and live as a throuple.

Speaking to Fox News, Anna and Lucy said: "We want to live like one person. We need everything to be identical: our clothes, our makeup. I need to follow her wherever she goes so if she walks into the next room, I have to. We have to do the same steps, too."

And when it comes to sharing a bed, there is a specific sleeping arrangement the trio follow.

"Lucy is always on the left side, Anna is always on the right, and Ben is in the middle," they added.

But despite the situation being far from a conventional one, it seems to work for all three of them.

Lucy explained: "We had separate boyfriends in the past and it did not work. We always have to have the same partner. When we had separate partners they always tried to separate us. It destroyed everything because we never want to be apart. For us sharing a boyfriend, it’s a lot easier for our lives.

"If I get pregnant, I would like Anna to be pregnant because we want to experience pregnancy together, so that’s Ben’s job. It’s going to be hard. But there’s treatments and new technology out there that would help us."

What's more, Lucy revealed that boyfriend Ben is nothing short of the pair's "soulmate".

Elaborating on their relationship to The Post, Lucy recalled how Ben has never judged them. "That’s how it’s been from Day 1. There’s never been any jealousy," she said. "I don’t know how we had separate boyfriends. People can judge us how they like — this is how it works for us."

Anna then added: "When she goes to the toilet, I come with her; when she has a shower, I come with her. You name it and we do it. We’re never apart. "
