In recent years she's embraced yoga, wellness and quiet nights in.
Yet Kate Moss proved she hadn't completely lost her love of partying as she stayed out at the Chiltern Firehouse in London until 3am on Thursday morning.
The 50-year-old supermodel - who has embraced sober living - did look ready for bed, however, as she left the celebrity hotspot alongside friend and socialite Emma Thynn, Marchioness of Bath.
Despite her tiredness she did manage to last longer than her younger sister Lottie, 26, who onlookers claim did not stay long at the bar.
Yet it was no doubt still enough time to celebrate the end of their three-year feud, having made up after attending their father's 80th birthday celebrations this week.
Kate looked effortlessly stylish for her night out in a black top embellished with sequins and featuring a sheer panel on the chest.
She teamed the garment with cigarette trousers and black pumps, layering up with a khaki blazer.
Lottie also looked casually chic for her brief appearance, teaming a white top with jeans and a leopard print jacket.
The joint outing signalled all was still well between the pair following their surprise reunion at their father Peter's birthday, when Kate made a point of posing alongside her younger sister in the photos taken at The Griffin pub in Sussex.
It was a pivotal moment for the pair who have not been pictured together in years, with Lottie previously claiming Kate 'doesn't even reply to my texts', despite once being so close that Lottie was a bridesmaid at Kate's wedding and even moved into her sister's Cotswolds mansion during the Covid pandemic.
However, tensions soon grew over Lottie's wild ways that saw her regularly taking drugs five times a week, which was a huge red flag to Kate.
Kate's love of boozing, which reportedly extended to flutes of prosecco at 8am and glasses of wine and vodka at lunch, saw friends coin her the nickname 'The Tank', but in recent years she's embraced yoga, wellness and quiet nights in.
Their lifestyle clash came to a head between the pair during lockdown, when Kate invited Lottie to stay at her Cotswolds mansion.
An insider told Page Six: 'Kate was frustrated because Lottie kept on wanting to drink and posting sexually provocative stuff on Instagram all the time.
'It isn't easy for Kate to be around people who are drinking, and she definitely won't be around anyone who is using cocaine.'
Kate was famously dubbed 'Cocaine Kate' when she was photographed snorting the substance in 2005, while dating Pete Doherty, who has made no secret of his own past drug use and addiction to heroin.
When Lottie finally departed the Vogue cover star's home 'in a foul mood', she reportedly left behind two bottles of her sister's favourite bottle of wine which was interpreted as a 'f*** you' gesture.
The roots of the rift between the sisters seem to originate with the large age gap between them.
Lottie is the daughter of Kate's father, travel agent Peter Moss, and his second wife, Norwegian Inger Solnordal, and was raised in Haywards Heath, West Sussex.
By the time she was born in 1998, Kate was already at the height of her fame as a catwalk model and had enjoyed a high profile romance with Johnny Depp.
Given her older sister's profile, it was no surprise when Lottie followed in her footsteps and signed with Storm Management in 2014 and began a mainstream modelling career.
And Kate seemed to give Lottie's career her seal of approval.
That same year, the pair were spotted side-by-side at fashion shows, including a Topshop runway show in 2014.
Meanwhile her first photoshoot was published in Teen Vogue, and she had her first full editorial not long afterwards in Dazed & Confused, a magazine which was co-founded by Kate's ex-husband, Jefferson Hack.
At one point it seemed like Lottie was on course to reach supermodel status in her own right, with modelling gigs for Chanel and Sonia Rykiel, an ad campaign for Calvin Klein and a Vogue Paris cover.
Aged 18, she was invited to Cannes as a guest of Dior and Chopard, while completing her A-levels.
Despite public perception that her famous older sister must have boosted her career, Lottie later insisted the opposite was true.
When questioned on if she asked her big sister for advice when she entered the world of modelling, the Only Fans content creator confessed the two hadn't even been close when she was a child.
'No, we just never really spoke honestly. It's always been that way, I never was sad about it really,' she said.
'You know obviously it's not great to hear that someone doesn't really care for a relationship with you... but you know we would see each other at Christmases and things like that and play family a little bit.'
Explaining her estranged relationship with her fashionista half-sister, Lottie revealed she had 'never really known' Kate, adding: 'It wasn't like I was losing someone.'
