Photos: Identical twins who share the same bed and boyfriend vow to fall pregnant at same time as their bodies ‘must be the same’

Identical twins who share everything including a bed and their boyfriend, have vowed they will try and fall pregnant together as well.

Anna and Lucy DeCinque, 30, from Perth, have spent nearly $250,000 on cosmetic enhancements to look more alike – including lip fillers, breast implants, and fake eyebrows and eyelashes.

The pair have both been dating electrical mechanic Ben Byrne, 32, for four years and have claimed they must have children together as their ‘bodies need to be the same,’ news.com.au reported.

‘We would have to be exactly the same — even if we went through IVF at the same time,’ they said.

Although Lucy and Anna are not ready to fall pregnant yet, they said they ‘love children and kids love them.’

The twins will appeared on SBS’s Insight program on Tuesday to discuss how identical twins change and develop as they get older.

According to the program, identical twins share 99.9 per cent of the same DNA and their intellect, sexuality and health can show genetic versus environmental factors.

‘If she walks a few metres, I need to walk a few metres because we have to burn the same calories,’ Lucy told the program.

‘Our diet is identical. Our food has to be identical. The same glass of water we measure. The same size of chip packets we have to measure.’

The pair said they feel as if they ‘don’t exist’ if their sibling is not with them.
