Cara Delevingne has sparked concern amongst fans and those close to her of late.
The 30-year-old has caused worry for her health following a series of bizarre appearances in recent weeks – as she appeared shoeless and disorientated before boarding Jay Z's jet and later disembarking before the plane took off.
Earlier photos saw Cara smoking from a pipe before heading into a sex shop.
Her worried family have reportedly been planning an intervention while Cara's sister Poppy is said to have rushed to her side.
Cara began modelling from the age of 10 before quitting at the age of 24 in 2016.
Writing for Time MOTTO, she explained of her decision: "Yes, your career is very important – but it's not the most important.
"Of course I was proud of my accomplishments, but I wasn't genuinely happy."
However, Cara isn't the first model to have struggled with life after finding fame through modelling.
Here, we take a look at the models who have have public struggles over the years.
Kate Moss
Kate has enjoyed modelling for a series of big name brands including Calvin Klein, Levi's and many more.
But, allegations of drug use saw her lose out on work – after she allegedly began abusing drugs after she began dating Johnny Depp in 1994.
In 2005, Kate was photographed snorting cocaine while in a recording studio while dating Pete Doherty.
The model, 48, lost work with Burberry as a result of the snap as Chanel, Burberry and Gloria Vanderbilt all axed her, which was predicted to have lost her as much as £4 million a year.
She was also nicknamed The Tank, according Maureen Callahan’s Champagne Supernovas book, for her partying ways.
But, the model has since turned her back on her partying days and is now sober.
Earlier this year, Kate poked fun at her cocaine days as she attended her Diet Coke collaboration party in June.
Asked by an audience member how she felt about her new role, The Sun reported Kate quipped in response: "Well, I have always loved coke."
Lottie Moss
Kate's younger sister Lottie has also struggled with the drug, and went to rehab for a "really bad" addiction.
The 24-year-old told her podcast Call Her Daddy earlier this year: "I just thought it was normal and I was going to these events and parties and I was exhausted, that was the only way I was getting through it.
"A lot of the time I would be showing up to set and I would not be happy and I didn't want to do it, I'd be crying my eyes out and they said, 'we'll just get you some drugs, you can have a drink and then you'll be fine'."
Naomi Campbell
Supermodel Naomi, 52, also had her fair share of public drama over the years.
Naomi, who began modelling from the age of 15, has had a series of public ordeals over the years after saying in 2000 she never wanted to be known as a "nice girl".
She told ABC America at the time: "I find that a little boring."
As well as her modelling skills, she also became known for her temper.
In 2006 she threw a mobile phone at a house keeper and admitted assault in a New York court, for which she was sentenced to five days cleaning toilets and mopping floors.
Naomi is also banned for life by British Airways after a row with staff at Heathrow Airport over lost luggage. However, she was allowed to fly with the airline five years later.
Naomi has appeared to chill out in recent years and became a mum at the age of 50 in May last year.
Bella Hadid
The 25-year-old model recently opened up about her past struggles with alcohol.
At age 17, Bella was arrested for driving under the influence as she was double the legal limit.
Last year, Bella decided to quit drinking after a scan showed how it had been impacting her brain.
She told InStyle: "My social anxiety was something that slowly crept up on me as I grew into my twenties.
"It got harder for me to go out without having one drink to calm my nerves, which made me not want to go out at all so I was just hibernating between jobs."
Bella revealed she occasionally drinks Champagne but avoids spirits to achieve "moderation".
Jaime King
The actress and former model was discovered at age 14 in 1993 and appeared in Vogue and Harper's Bazaar and also modelled for Dior and Chanel.
During her first modelling job, Jaime began using heroin at age 14 as she was offered the drug at the shoot.
However, she was shocked into kicking the habit after her boyfriend Davide Sorrenti – who was famous for glamorising heroin chic in the 1990s – died of a kidney ailment reportedly caused by excessive heroin use in 1997.
She told the New York Daily News in 2015: "I was surrounded by drug abuse. It was something that was always there.
"The editor, the photographer, everybody was smoking or shooting drugs, so it was natural for me.
"I just thought that was the way things worked. Did I shoot heroin? No, I sniffed it."
Sophie Anderton
Model Sophie, 45, became addicted to cocaine and dropped six-and-a-half-stone as a result and blew £400 a day on the drug.
Sophie, who shot to fame as she graced billboards across the UK as the face of Gossard’s Wonderbram gave up cocaine in 2004 and previously told the Independent: "Drugs are so accessible within the industry, and it is very difficult to steer completely clear of them."
She added: "The enormous pressures to stay thin in the industry almost lend themselves to take a substance well known for suppressing appetite."
Sophie then got clean and later told Sunday People in 2013: "I could have carried on down the road I was going down and been one of many people I know who died from drugs, or I could change my life.
"I was a dreadful person. The drugs made me lie, they make you the opposite person of who you’re meant to be. Cocaine is evil. I was vile but I was a cocaine addict."
