They are the obsessive twins who are so close they have not been apart for more than 30 minutes in 15 years – and even once shared the same boyfriend.
Amy and Becky Glass, 46, share everything, including a joint Facebook profile, a bedroom, the same mobile phone and a business they run together in a shared home office.
They go to extremes to be mirror images of each other – and wear the exact same outfit every day in slightly different colours.
The pair say they are not interested in relationships anymore, and feel like they are married to one another.
Incredibly, Amy and Becky have been measuring out every bite of food and sip of drink using scales and measuring cups for 19 year, to ensure their body-shapes and weights stay the same.
For the past 19 years Amy and Becky have been eating and drinking the same amount of food – carefully weighing out meals and pouring drinks using measuring cups.
The sisters, from Los Angeles, USA, said: ‘It’s really like we’re one person in two bodies.
‘We go bite for bite – and we warn each other when the last bite will be so we know when the other is full.
‘If Becky doesn’t want dessert, I won’t have it . We either talk each other into it or out of it.
‘At one point I weighed a little bit more than Becky, so people would say that I was the bigger twin and we hated it.
‘We decided to go on diets and we have both weighed the same weight ever since.’
Growing up, their mother dressed them in identical outfits.
In high school they continued to dress alike, but decided to stop when they were bullied for it.
After starting college at Rutgers University in 1986, in New Jersey, they went back to matching because they hated looking different.
Amy said: ‘We felt completely off being in different outfits – I felt like more of myself when I matched my sister, it was natural.
‘But we decided to make a slight twist – choosing to wear the same outfit in two colours.
‘We prefer it so much, because we are the same size, so we can swap clothes.
‘It’s like we get two outfits each every time we shop, because we can mix and match on different days.’
In 1993, they met a their ex-boyfriend Chris at a party.
Amy said: ‘We dated at the same time, all three of us – he was always taking both of us out.
‘He was the one guy that both of us had sex with, however, most of the time we took it at the same times.
‘As twins with a connection, we kind of just knew instinctively who was in the mood that night
