Anna and Lucy DeCinque, 30, from Perth, follow identical diets and exercise routines and have spent nearly $250,000 (£177,000) on cosmetic enhancements – including breast implants and fake eyebrows – to look more alike. They even have the same boyfriend – 32-year-old electrical mechanic Ben Byrne – and plan to fall pregnant at the same time because their ‘bodies need to be the same.’

Before Lucy and Anna underwent extensive cosmetic enchancement, they were already diffult to tell apart

They spent nearly $250,000 on cosmetic enhancements to look more alike - including lip fillers, breast implants and eyebrows tattooing.

The pair have both been dating electrical mechanic Ben Byrne for four years.

"We want to weigh the same, we have to have our bodies the same. If we did a twin study and came out different, we'd be so upset."

They are very proud after taking part in a Japanese prank TV show, and outwitting Japanese face recognition technology which could not tell their faces apart.

"But if I got pregnant Lucy would definitely get pregnant straight way - because our bodies need to be the same." Anna said.

The three share a super king-sized bed.

"On the bright side I get double the love." the boyfriend said, no wonder he is smirking.
