Identical Australian twins who share the same bed and boyfriend and are never more than a few metres apart, have been named the World's Most Identical Twins after taking Japan by storm.
Anna and Lucy DeCinque who have spent over $250,000 on the same cosmetic surgery procedures to ensure they look identical, fascinated the producers of a Japanese television prank show who discovered them on YouTube.
The 28-year-olds from Perth in Western Australia, who were born just one minute apart, were invited to fly over and participate in the show which saw them playing tricks on the public and competing against a Japanese set of twins who simply couldn't compare to their extreme measures.
'They would go to the shops without each other. See, we wouldn't do that. We wouldn't leave each other by ourselves. And they didn't sleep in the same bedroom,' the DeCinque twins told Channel Seven of their competitors.
After even a computer failed to spot the difference between Anna and Lucy, the duo embraced the title of the World's Most Identical Twins.
'It's been proven in Japan and they did the challenges and we proved we are the world's most famous identical twins,' they told Channel Seven's Sunrise.
'It's a great tag line for us.'
The women also revealed some of the daily measures they go to in order to maintain their similarities, including eating the same type and amount of food and never leaving each other's sight.
'When she gets full, I'm full as well. When she stops eating, I'll stop eating,' they said, adding: 'We want our bodies to look the same; we want to weigh the same.
'We are never more than a few metres apart, wherever my sister goes, I go as well. We follow each other.'
'We argue every day, but over little things. It's natural… but we get over it. We're best friends so we never want to lose each other.'
They also touched on some of their more extreme measures, including the hundreds of thousands of dollars they've spent on cosmetic surgery procedures including lip fillers, breast implants and fake eyebrows and eyelashes.
'We've always been identical from an early age, we just wanted to get the same procedures because we want to do everything together and we want to look exactly the same,' they said.
Anna and Lucy, who live at home with their mother, also share a boyfriend, which they believe is a perfect situation for a relationship. Though the two have had separate love interests before, they have always been brothers, or at least best friends.
When asked about the difficulties of sharing the one boyfriend, the twins responded with 'it works easier for us'.
'We've had separate boyfriends in the past and it hasn't worked, but now it's much easier and its great.
'We're with each other 24/7, me and my sister; it's just easier to share a boyfriend because we're always together.'
Their current boyfriend is electrical mechanic Ben Byrne, also from Perth, according to PerthNow.
'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,' Lucy said.
'We have the same taste in everything, so obviously we're going to like the same boy too. We're all together when we have sex, and if we like the same guy, so be it. Every date had to be a double date. It's always double or nothing.'
From an early age Anna and Lucy were inseparable. The sisters went to the same nursery, primary and secondary schools, before enrolling on a beauty course at college together.
The sisters revealed that they were so close even their parents have struggled to tell them apart, especially their father Luigi, who died in 2010.
Lucy said: 'Our mum has always been able to tell us apart. But, our dad, not so much. He would say, 'Which one are you?''
Only a small mole on Lucy's cheek and a scar on Anna's forehead separate the two. But, those slight differences go unseen by most – including ex-boyfriends.
Lucy says: 'We've had fun, especially when we were younger. We would swap boyfriends, if we were bored.
'Like, even on the telephone, if I didn't want to talk to my boyfriend, Anna would take the phone and pretend to be me. We would play games like that, and the other person never realised.
'We've settled down a bit now.'
The childhood accident – a bump in the bathroom - that caused Anna's scar is one of the few things the sisters didn't do together.
Since then, everything Anna and Lucy have done has been in sync. From living together, to the job they share - working with the elderly - the twins are never more than a few metres away from each other at all times.
'We never get tired of each other, even though we're always together,' said Lucy.
'Of course, we argue. When you're with someone 24/7 you're going to have arguments and get on each other's nerves. We always make up, though.'
Anna and Lucy's unique bond has only grown as they got older. Aged 12, the sisters opted for different hair styles, with Anna going for a longer cut, but the streak of individuality was short-lived.
When their father Luigi was diagnosed with cancer and remained housebound, the girls became even closer. They quit their beauty course and stayed at home to look after their dad, until his death five years ago.
That same year, when the girls turned 24, they both decided to have breast enlargements after, they say, being inspired by Kim Kardashian's. The two from a BB cup size to DD.
They now undertake an extensive joint beauty regime to maintain their appearances. Once a week, Anna and Lucy take advantage of infra-red saunas, microdermabrasion and skin peels to maintain the mirror image. They also follow the same exercise routine and keep an identical diet.
Anna said: 'We like looking after ourselves, what girl doesn't?'
The sisters, who don't drink or smoke, take great pride in their appearances, and wear a new outfit every Saturday night.
Their wardrobe is full of body-hugging size 8 mini-dresses and hefty heels.
Lucy said: 'We never wear the same outfit twice when we go out. Everything has to be new. When we go clothes shopping, Anna will already know that I like a certain top.'
'We always know what the other is thinking,' Anna added. 'We stopped buying gifts for each other, because we ended up buying each other the same thing.'
After caring for their father while he was ill, Lucy and Anna applied for a job in aged care, serving meals to the elderly.
Their joint application was successful and they share the position and take home one salary.
The money, which ends up in the same handbag – carried by Lucy, goes towards the twins' beauty regime.
And, when the twins step out of the sauna and walk down the street, attention is never far away.
Anna says, 'When we go out, we get so many guys saying they want to marry the both of us or date the both of us.
'And we always have girls coming up and saying "where do you get your clothes from?" They love our style.
'And we feel each others' pain too. If Lucy's at the dentist, I will feel her pain.'
While the girls have been warned that their extreme closeness could lead to serious problems in the future, especially if one of them decides to get married and move away or if one of them dies, the twins remain unfazed.
Lucy says, 'We can't imagine a day when we're not in each others' company. And, to be honest, I don't think that would ever happen.'
