The ‘World’s Most Identical Twins’ Share Everything—Including Their Fiancé
Introduction
Imagine meeting someone, feeling an instant connection, and then discovering that your twin sister feels exactly the same way. Now imagine that instead of choosing between them, that person chooses both of you. This is the reality for Australian twins Anna and Lucy DeCinque, who have been dubbed the “world’s most identical twins” . For over a decade, they have shared not just a wardrobe, a bed, and even bathroom routines—but the same man .
Their story challenges conventional ideas about love, relationships, and identity. While most people struggle with jealousy in monogamous relationships, these sisters claim to have never experienced envy toward one another . Their unique arrangement has captivated millions, sparking debates about polygamy, sisterly bonds, and the limits of love.
Who Are Anna and Lucy DeCinque?
Anna and Lucy DeCinque are Perth-based sisters who gained international fame after appearing on the TLC series Extreme Sisters . Born on July 19, 1985, the twins have taken their bond to extraordinary lengths . They dress in identical outfits, eat precisely measured meals, undergo the same cosmetic procedures, and even use the bathroom and shower together .
Their commitment to sameness goes beyond mere coincidence. They have described themselves as feeling like “one person” and experience separation anxiety when apart . They measure their food and drink to maintain identical body weights and have had matching fillers and other cosmetic enhancements to preserve their identical appearance .
The Relationship That Shocked the World
The twins met their fiancé, Ben Byrne, who is himself a twin, through social media over 11 years ago . The story of how their relationship began is as unconventional as the arrangement itself. On their first night meeting Ben, both sisters kissed him simultaneously and realized they both liked him .
Anna and Lucy then sent Ben a Facebook message with a rather direct question: “Can we share you?” . Initially, Ben thought it was a joke, but he eventually agreed . Since then, the trio has been together for over 14 years . Ben proposed to both sisters in June 2021 with two identical rings at the location of their first date .
How the Relationship Works
The sisters have established clear rules to maintain harmony. Ben must treat them equally at all times—if he kisses Anna, he must kiss Lucy immediately afterward . This rule has been in place from day one and has reportedly prevented jealousy .
The sisters claim there is “no jealousy in this relationship from day one” . When asked about their intimate life, they have confirmed they share an oversized king bed and are “never apart” . According to the twins, their relationship works because all three of them are equally committed and satisfied with the arrangement.
Why They Chose This Lifestyle
For Anna and Lucy, sharing a partner was a natural extension of their inseparable bond. They have explained that having separate boyfriends never worked because partners always tried to tear them apart . As Anna put it: “Sharing a boyfriend for us means we get to be together all the time” .
They also acknowledge that this arrangement may seem unusual to outsiders. However, their stance is simple: “People can judge all they want, but we’re just doing what makes us happy” .According to Ben, the twins consider themselves one team, so he chooses to treat them in the way they are most comfortable with.
Challenges They Face
Despite their happiness, the trio faces significant obstacles. The most pressing issue is that polygamy has been illegal in Australia since 1961 . Ben has called this “our biggest hurdle” . The twins have expressed a desire to change the law, saying: “If we can change the law and the government, we’d love to marry Ben” .
Another challenge involves their dream of motherhood. The twins want to experience pregnancy at the same time . Their doctor has told them they have a 1 in 36 chance of naturally conceiving simultaneously . They have explored IVF options but have put their plans on hold due to difficulties . Lucy has said: “Motherhood is beautiful but if I’m not doing it with my sister, I’m not doing it at all” .
Public Reaction and Criticism
The DeCinque twins have amassed over 140,000 Instagram followers and continue to share their unusual lifestyle . While many fans support them, they have also faced criticism. Some viewers have called their bond “obsessive” . The twins themselves have acknowledged that appearing on Extreme Sisters made them “more extreme” and “made us realize how much we love each other and really can’t live without each other” .
Even Ben has expressed frustration at times. He has worried that their obsession with being identical has caused them to “give up on a lot of things,” including career opportunities and their baby plans . When the twins quit jobs at an Italian restaurant because it was causing them to “grow apart,” Ben questioned how their lifestyle would affect their future .
Conclusion
The story of Anna and Lucy DeCinque is remarkable not just for its strangeness, but for what it reveals about human connection. In a world where relationships are often defined by conventional boundaries, these three people have created a dynamic that works for them, despite legal and social obstacles.
Whether one views their arrangement as inspiring, troubling, or simply baffling, the twins’ message is clear: love doesn’t always fit into neat categories. Their commitment to each other and to Ben has endured for over a decade, and they show no signs of changing course. As they have said: “We feel like we’re one person. We can never, ever be apart and we would never choose to be. This is how we want to live our life” .
