Australian twins Anna and Lucy DeCinque have gained international attention for living what they describe as a completely synchronized life. The sisters, who often call themselves “the world’s most identical twins,” share nearly everything—interests, routines, and even their long-term partner, electrician Ben Byrnes.

The trio’s unusual love story began in 2011, and Ben eventually proposed to both women during a quiet picnic. He presented matching rings, symbolizing his commitment to their united relationship. Moreover, the twins say Ben has always treated them equally, a quality they believe makes their arrangement work.

Anna and Lucy’s daily lives reflect a remarkable level of coordination. They often eat the same meals, mirror each other’s schedules, and strive to match their appearance as closely as possible. Over the years, they have invested heavily in cosmetic procedures to maintain their identical look, though they have reversed some treatments they felt went too far.

Their close bond also shapes their hopes for the future. The sisters have spoken about their dream of becoming mothers at the same time, though they acknowledge the challenges ahead. If needed, they may explore medical options to increase their chances.

However, one major obstacle remains. Australia’s marriage laws do not permit the three to wed. Despite this, Ben has promised to support whatever path makes the sisters happiest, including considering ceremonies abroad.

Public curiosity often surrounds the private details of their relationship. Yet Anna and Lucy emphasize that their arrangement is built on mutual respect and shared choice. As they put it, this is simply the life that makes sense for them—and they plan to navigate it together for as long as they can.
