Kate Moss and her half-sister Lottie were once so close that they lived together during the Covid lockdowns.
Now Lottie has revealed she has become so estranged from her family that even her mother no longer speaks to her.
The aftermath came when Lottie, 26, began stripping naked for the adult subscription website OnlyFansafter moving to Los Angeles for 2021.
'I had a feeling people in the UK wouldn't be as forgiving, but it was nothing like how I felt when I came back,' she says. 'I lost a lot of friends from the modelling industry. My mum didn't speak to me for weeks and my family were a bit upset about it.'
Lottie grew up in Haywards Heath, West Sussex, with her Norwegian mother, Inger. She is the second wife of travel agent Peter Moss, the father she shares with Kate, 50.

Speaking on her new podcast, Dream On with Lottie Mossshe adds, “There are so many OnlyFans girls in LA and so many porn stars in LA. People just accept them into society, and people are cool with them, and no one asks too many questions about it.”
The 26-year-old, who was paid £20,000 a year at Bede School, added: 'Then I moved back to London and it all became real for me. All my friends thought I was having a serious mental breakdown.'
Lottie was a bridesmaid at Kate's wedding and when she started modeling for Teen Vogue at the age of 16, it seemed likely she would follow in her sister's footsteps.
She now says living in Kate's shadow made her “depressed” and forced her to stop working with expensive fashion houses.
'For years, as a model, I was just told who I was, and I was told, “This is who you are, you're Kate Moss' sister and you're going to be part two of her,” and that was absolutely not me.'
Although she previously starred in an advertising campaign for Calvin Klein, something most models would kill for, Lottie says she gets more satisfaction from her work as a 'content creator' for OnlyFans.
'People think I got into it because I was in a bad phase of my life and everything was going wrong, but it was the opposite,' she insists. 'Modelling represented something I wasn't really into and then when I found Only Fans I met all these girls who looked like me. I always wanted to be a bit more daring and I always wanted to show my body.'
This comes after Lottie revealed she never really had a relationship with her supermodel brother and opened up about their complicated family dynamic.

However, she revealed in November last year that she never had a close bond with Kate (pictured: Lottie in a racy black outfit)
“We've never really spoken honestly. It's always been that way, I've never really been sad about it,” Lottie said of Kate (pictured at the King's Trust Global Gala in May)
Lottie was a guest on the Matt Haycox Show Podcast last November and admitted that she has never had a close bond with Kate.
When asked if she asked her older sister for advice when she entered the modeling world, the Only Fans content creator confessed that the two weren't even close when she was a child.
“No, we never really spoke honestly. It's always been that way, I've never really been sad about it,” she said.
“You know it's obviously not nice to hear that someone doesn't really care about being in a relationship with you… but you know, we would see each other around Christmas and stuff like that and play family a little bit.”
Lottie explained how estranged she was from her relationship with her fashion-conscious half-sister. She revealed that she 'never really knew' Kate, adding: 'It wasn't like I lost anyone.'
“It was never really that she chose to leave. She's 20 years older than me and has every right to live her own life. She doesn't have to deal with me.”
Lottie previously claimed she earns around £30,000 a month from her porn broadcasts, but says she cherishes every penny after spending big as a teenage model.
Lottie confessed: 'I spent every penny of what I earned at the time, everything, and that's one of the things I regret most in my life.
'Now I have money in my account, but to be honest, I struggled for years because I was just spending money.
'There was a long time when I was 18, 19, 20 years old, when I was just making money and not looking at the price tags. I was just spending money.

'I thought it was an unlimited flow of money, but that turns out not to be true!'
Last March, she criticised those who hold the “common misconception” that she comes from a rich and famous family, amid online nepotism rows.
'I think a common misconception is that because Kate, who is 24 years older than me, is rich and famous, my family was too.
“But of course it was her money and her fame, not ours,” Lottie wrote in Newsweek.
She continued: 'How can I tell people that I don't know her and that she doesn't respond to my messages?
I find the whole 'fake baby' concept really weird. There are so many people in the world who have had clear advantages in their careers because of who they know or who someone in their family is, and it's not just famous people.
