Anna and Lucy DeCinque are close. Really close.
So close, in fact, that the identical twin sisters share a boyfriend. Oh, and they want to both carry his babies at the same time.
The Australian women, who have claimed the title of 'world’s most identical twins' aren’t shy about their unusual lifestyle, and frankly, they really don’t care what anyone else thinks.
They even star in a TV show about it: Extreme Sisters on American network TLC.
Since 2017, and on the TV series, they have spoken about their hope to fall pregnant at the same time.
Lucy and Anna, 38, dress alike, eat exactly the same meals, do the same workouts and have undergone the same plastic surgeries to keep their bodies, and their lives, as identical as possible.
"We do everything together. We’re never more than a few metres apart, we work [together]. We share everything," they told a UK talk show in 2016.
"When she goes to the toilet, I come with her; when she has a shower, I come with her," Anna told the New York Post.
"You name it and we do it. We're never apart. I don't think we'd function without each other. We have separation anxiety. We're bound to each other."
But perhaps the most surprising aspect of their relationship is that they share a boyfriend.
Their relationship with Ben Byrne – who is a fraternal twin himself – is not new. They've been dating for more than a decade.
"It was great from the start. We just hit it off straight away. It’s so much easier for us to share a boyfriend," Anna told the New York Post.
"I don't mind that he comes over to kiss Lucy, because then he's going to kiss me."
