If you've been on the Internet at all in the last few years, you've probably heard of the 'world's most identical twins', Anna and Lucy DeCinque.
The dynamic duo hit the headlines over the revelation that they share pretty much everything in life.
Not only did they get the exact same cosmetic surgeries to ensure they stay physically identical, but they also share the same boyfriend and recently revealed their intention of getting pregnant at the exact same time.
And if you assumed the bedroom is where these two draw the line, you'd be wrong, because in their latest update, the 33-year-old siblings from Perth, Australia, have revealed they take it in turns to have sex with their shared boyfriend of eight years, Ben Byrne - and they're both in the bed when it happens. *shivers*
Yes, during the latest episode of Australian TV programme Hughesy, We Have a Problem, the DeCinque sisters discussed their relationship with the mechanic who they first started dating in 2012, revealing that all three share a king-size bed.
When host Dave Hughes asked if they were both present when they did the deed, they replied 'yes'. Clearly they didn't get the memo that says three's a crowd.
Lucy chimed in: "There's no jealousy in the relationship - if Ben will kiss Anna, he will kiss me Lucy."
"Ben accepts us. He doesn't mind that we dress alike and want to be together; he doesn't judge us," added Anna.
"We always have each other's backs... He gets double the love; double the attention."
Although their love for each other can't be made official, as polygamy is banned under the Australian Marriage Act 1961, the three partners are hoping the twins will conceive at the same time.
While it's possible, particularly considering the latest revelation about their bedroom antics, the technicalities are rather mind-boggling. The children would be both half-siblings and cousins - so would Ben be both the father of his children and an uncle to them? Guess they'll cross that bridge if and when they come to it.

Prior to their familial situation, Anna and Lucy spent $250,000 on cosmetic surgery to make themselves look more alike, and they go to extraordinary lengths to make sure everything stays identical.
Lucy said: "If she goes to the toilet, I have to go at the same time because we eat and drink the same, we shower together, we're just never apart.
"It's stressful being us, we have to measure our plates, everything has to be identical."
Certainly sounds stressful - and for Ben too, as it's on his shoulders to ensure the pair get a bun in the oven at the same time.
In a previous interview, the twins said: "It's gonna be another challenge. It's all up to Ben, I think. There's a lot of pressure on Ben."
Poor old Ben - he's certainly got his work cut out for him.
