Identical twins Lucy and Anna DeCinque, 31, have revealed that they plan to get pregnant at the same time, with the same boyfriend.
The DeCinque twins made headlines earlier this week after they defended their choice to share one boyfriend, Ben Byrne.
The pair, who do everything together, have now revealed they plan to get pregnant at the same time too.
One twin told Australian TV show 'Insight': "If she got pregnant I'd make sure I got pregnant."
The reason? To keep their bodies the same.
Despite them wanting to experience pregnancy at the same time, they don't expect their children to be born at the same time or on the same day.
"[We] just have to be pregnant at the same time," one said, according to Stuff.co.nz.
While the other added: "We just want to be the same in everything."
The twins recently defended their decision to share a boyfriend on Australian TV show 'A Current Affair', which aired on 10 March.
Speaking about their three-way relationship, they said: "People won't agree to it and it's not natural maybe some will think, but he's happy, we're happy, our family and friends accept it."
The pair said they'd had separate boyfriends in the past, but it hadn't worked because of their closeness. They added that sharing one now "just works".
"Because we're with each other 24/7, every single day, every minute of our life...it's just much easier," they said.
"He's a twin and he understands the bond. He understands we want to be together all the time.
"He never favours one twin, if he kisses me, he'll kiss my sister straight afterwards. There's no jealousy."
They explained that the three of them live together, with their mother.
The twins do everything together and wanted their bodies to be identical so much that they've spent thousands on cosmetic surgery.
They also share a job, car and Facebook account.
The pair, who have been in a relationship with 32-year-old Ben Byrne for four years, said of their beau: "Yeah, he's got a lot of work. He needs twice the energy."
Lucy and Anna appear on a two-part show called 'Insight' which looks at how identical twins change and develop as they get older.
The first episode was broadcast by SBS on Tuesday 15 March, the second episode airs on Tuesday 22 March.
