You’d have to have a forensic eye to tell Anna and Lucy DeCinque apart.
The twins have been dubbed the “world’s most identical sisters” due to their matching appearances and lifestyles.
Not only do the pair share the same facial features and fashion sense, they are also dating the same man.
While this may seem like an unusual set-up for many, the 33-year-olds are very happy with the relationship.
This week, they appeared on daytime TV to announce their plans to marry their partner, as well as their dreams to fall pregnant at the same time.
Anna and Lucy have been dating Ben Byrne, 35, for six years.
The Perth-based pair were immediately drawn to the mechanic due to his “genuine” interest in them.
As a twin himself, he also understands their bond.
The trio now live together and enjoy a polyamorous relationship.
Previously, Lucy explained why this agreement works so well for the trio.
She said: "We're with each other 24/7, me and my sister; it's just easier to share a boyfriend because we're always together.
"It's not really weird to us. We have one boyfriend and all three of us share the same bed.
"For guys, in their hearts and dreams, they want two girlfriends.
"We have the same taste in everything, so obviously we're going to like the same boy too.”
The siblings are even considering getting pregnant at the same time, even though they have no plans to start a family at the moment.
Anna remarked: "If I got pregnant Lucy would definitely get pregnant straight way – because our bodies need to be the same.
"We would try to make that happen, definitely.
"We are not trying right now. We love children and kids love us – but it's not the time for us.
"We would have to be exactly the same – even if we went through IVF at the same time."
The twins’ mother is very supportive of these plans and hopes her daughters will fall pregnant naturally.
This week, they told Australia’s Today programme: “Our mum’s actually convincing us to give birth naturally…
“We need to be pregnant at the same time.
“How is that going to work?
“It’s going to be another challenge. There’s a lot of pressure on Ben.”
