Two Australian identical twins, who are engaged to the same man and are planning to have babies at the same time, have caused debate online after revealing they would both be mums to each other's child.
Perth sisters Anna and Lucy DeCinque have been dating 37-year-old electrician Ben Byrne for 10 years and recently got engaged during an episode of TLC's Extreme Sisters, a doco showing their unusually entwined lives.
In the most recent episode, the 35-year-olds were seen having a conversation with two family members about how their plan for their pregnancies would work, and were taken aback by their response.
"We would look after each other's baby," Anna tells their mum.

"I'll probably think what's mine is yours, what's yours is mine, that's how it would be," Lucy agrees.
Anna then explains neither of them would think, "this is my baby and that's your baby", with Lucy agreeing, stating: "We would share babies."
But while the women – who have previously explained they believe they are "one person" wear the exact same clothes and eat identical meals – were confident in their decision, their mum and another family member opposed it.
"No, if Lucy had a baby, Lucy's the mother," their mum said.
"Of course a baby can have two mums, even if it seems strange to you it doesn't mean that you can have a say," one woman wrote.
"This is wrong on sooooo many levels," another said.
"I agree with them, babies can never have too much love and care," one person stated.
Others pointed out that their babies, who would genetically be siblings and cousins, would have the same DNA because Anna and Lucy share the same DNA and the father would be the same.
"Might not be for everyone but they aren't doing anything wrong," one commented.
While one mum said: "My kids have a mum and a step mum, having two mums that love you seems like a bonus to me."
There were a few commenters who agreed the set-up was unusual, agreeing it was "very strange". But most were on Anna and Lucy's side, stating: "It takes a village."
Last week's episode of the weekly doco show, that also features American identical twins Brittany and Briana Salyer who are married to identical twins Jeremy and Josh, saw Anna and Lucy get engaged to their joint partner Ben.
"Anna you mean the world to me and I want to spend my life with you and Lucy you mean the world to me and I want to spend my life with you too. I love you, I love you both," he said.
As Australia doesn't allow three people to get married, the trio are looking at other options such as Malaysia, Indonesia or parts of America, to make their three-way marriage work.
