Meet the world's most identical twins who spent $250k on surgery & share one boyfriend (PHOTOS)

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-old's 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.

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.'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.'

Their current boyfriend is electrical mechanic Ben Byrne
