Anna and Lucy DeCinque, from Perth, took to their popular Instagram page to share the snap of themselves in plunging white, strapless dresses with their 25,000 followers.
‘Feel like 2 BRIDES in this gorgeous dress plus it’s a PLAYSUIT,’ the pair – who have previously spoken about how they are in love with the same man – wrote.
Their post immediately sparked speculation they may have wed their shared partner, Ben – with one fan writing ‘Lovely twins!! Did you all get married? Lol!’
The identical duo haven’t been shy about their desire to marry Ben in the past.
A few weeks after celebrating their five-year relationship anniversary via their YouTube channel, the pair spoke openly about it.
‘We've been with him for five years so he's twinning and winning... We do want to marry the same man and his name is Ben,' they said in the clip.
'Many debate. Is it possible? Can it work? I don't really know. But we've actually heard in Tucson you can get married.'
They went on to discuss how a marriage proposal might work.
'He needs to get double of everything - two rings... And what wedding dress do you want to get?' they asked.
The threesome certainly appeared happy as they posed for on January 1 this year.
‘Here’s to many more years together and more memories with our beautiful man. Love you Ben,’ the pair wrote, along with two heart emojis.
