Anna and Lucy DeCinque, from Perth, Australia, have previously hit headlines for spilling the beans on their unusual lifestyle - having spent $250,000 (£194k) on cosmetic surgery to look more alike, and also revealing they share the same boyfriend.
The duo appeared on This Morning today to talk about how they plan to get pregnant at the same time with shared partner Ben Byrne, saying they want to try for a baby through IVF.
Presenter Ruth Langsford asked: "You literally do everything together including going to the toilet at the same time?"
The twins, who often finish each other's sentences and speak in unison, said: "We shower together we make up together we go to bed at the same time, we eat together, we're hungry together, everything is just the same.
"It could be obsessive but this is how we want to live our life, we live as one person."
Langsford then asked about how the twins were considering having children 'at exactly the same time'.
They replied: "We want to experience pregnancy together, we want to do everything in life together, we will die together, we'll grow old together."
When Ruth pondered how it was 'going to work', Eamonn quipped: "Ben will be knackered!"
The twins answered: "Maybe IVF if we have to go down that road, even freezing our eggs at the same time."
Many were stunned by the twins' plans. One viewer, who is also a twin, said: "This definitely makes us twins seem even more alien than we already do! I would never want to see my identical twin taking a shower, or share her boyfriend!"

Another said: "There are twins on This Morning who share the same man. Okaaay. What could possibly go wrong?"
Others were a little more open-minded, with one Twitter user saying: "So funny. Well they seem very happy, the twins!! Ben must be very fit lol. Good luck to them all."
