From humble beginnings to Hollywood. These stars may be dining on champagne and caviar now, but that wasn't always the case.
Rapper Cardi B made ends meet by stripping, singer Jewel was homeless and living in her car, and pop star Justin Bieber was so poor, he couldn't order a coke from the menu.
Here are the other celebrities who went from rags to riches.
Ozzy Osbourne's daughter Kelly shared a sweet family snap to celebrate her dad's birthday amid his current health battle.
"Yesterday was my Dadda's birthday although we kept it low key we had the best time," she wrote alongside the image on Instagram.
"We are always the best versions of ourselves when we are together. I love my family so much it hurts."
She added: "Dad you are the other pea in my pod. I love you to the moon and back."
Although between them the family share a staggering net worth of around $533 million, it didn't start out that way.
Osbourne grew up in a poor part of Birmingham, England where both his parents worked in a factory, his mum taking the day shift while his dad worked nights.
He was the fourth-born child, his parents later going on to have two more boys.
In a 2002 Rolling Stone interview, Osbourne opened up about how little his large family really had.
"We had a boiler house in the garden," he said. "You'd put a fire under this copper boiler, where you would boil the clothes to death.
"I used to sleep in a bed with one of my brothers. We had no sheets. We had to use old coats."
He explained that he chose to leave school at 15 years old, after struggling with dyslexia in an education system that didn't recognise it.
He went on to work in several different industries, including a job in a slaughterhouse and another in a mortuary.
"The formaldehyde was awful," he said. "I'd have visions of the dead people's faces when I got home.
"Then my mother got me my first musical job – I tuned car horns.
"You were supposed to do 900 a day. Can you imagine being in a room with that fucking racket?"
It wasn't until 1968 that Osbourne and three friends formed a band.
"We had a van full of equipment, and we'd go to gigs hoping the other band wouldn't make it, which happened several times," he explained.
"We used to play for nothing. We'd do wedding receptions."
One day when walking past a music theatre showing a scary movie, one of the band members pointed out how strange it is that people pay to be scared.
He then suggest the band try writing 'scary music'.
"That's when we came up with Black Sabbath," said Osbourne. "That was the fucking change of my life."
In 1978, Osbourne was fired from Black Sabbath because of his addiction to drugs and alcohol.
However, after meeting his now wife, Sharon, who helped him get his life straight, Osbourne has since gone on to have a long and successful solo career.
In 2019, Osbourne was diagnosed with Parkinson's Disease.
His condition has kept him off the stage for years, and forced him to cancel a highly anticipated gig earlier in 2023.
"My original plan was to return to the stage in the summer of 2024, and when the offer to do this show came in, I optimistically moved forward," the Rockstar said in his cancellation announcement.
"Unfortunately, my body is telling me that I'm just not ready yet and I am much too proud to have the first show that I do in nearly five years be half-assed."
Throughout his ongoing health battle, Osbourne has had his children and wife alongside him to help him through it all.
His wife, Sharon, accepted his ICON award from Rolling Stone Magazine on Osbourne's behalf in November.
"I am just so proud of him as a man as a musician," she said.
"It's been my honour to be on his coattails. I adore him. And you've just got no idea what this means.
"Ozzy is what rock and roll is all about. He's wild, he's fabulous, he's talented.
"He's like a f–king uncaged animal, and I adore him."
In an interview on The Kyle and Jackie O Show in 2016, Mila Kunis – who immigrated to the US from Ukraine at age seven – said she and her family used to eat meals of "ketchup soup".
"I grew up poor. My husband and I both did," she said, referring to her other half Ashton Kutcher. "[We] are very aware of what a dollar is worth. Nothing's been handed to us."
Despite Kunis and Kutcher now with a worth a staggering combined net worth of $US275 million ($598 million), the couple say they won't raise their children to be entitled brats and won't leave them an inheritance.
Selena Gomez's parents split when she was five years old and it was hard for her mother – who gave birth Gomez at age 16 – to put food on the table and pay bills on time.
In an interview with E! in 2011, the actress and singer recalled: "I remember my mum would run out of gas all of the time and we'd sit there and have to go through the car and get quarters and help her get gas."
Gomez helped provide for her family by working as a child star in Hollywood. She is now one of the most recognised faces in the world and is worth a massive $US800 million ($1,239 million).
Leonardo DiCaprio has never hidden the fact he grew up in a poor neighborhood in Los Angeles, where he was often exposed to drugs and violence.
But his life would change completely after he was cast alongside Robert De Niro in 1993 film This Boy's Life. He has since starred in The Aviator, The Great Gatsby and The Revenant, which won him the Best Actor Oscar in 2016.
As a major player in Hollywood, he is worth a mammoth $US300 million ($470 million).
Kelly Clarkson grew up in Texas and her parents divorced when she was six.
When old enough to do so, she moved to LA to pursue singing in 2001 but was forced to move back home when a fire tore through her apartment.
But Clarkson did not give up on her dream – the following year she auditioned for American Idol and became the first ever person to win the title. She is now worth $US45 million ($70 million).
Justin Bieber was raised in Ontario, Canada by his single mother, who worked various low-paying office jobs to raise the budding singer.
"I remember being poor and being teased by other kids," he admitted to Britain's OK! magazine
"I remember sitting in restaurants with my mother and she'd make me order water instead of soda. I remember so badly wanting to order a soda," he recalled. "And I also remember that when I got my first big pay cheque I was so glad to be able to use that money to take care of my mother."
The singer was discovered by manager Scooter Braun in 2008 and now Bieber is one of the biggest names around the world. He has $US300 million ($465 million) in the bank too, so he can now spoil his mum to his heart's content.
Eminem frequently moved from state to state with his mother after they were reportedly abandoned by his father.
After eventually settling in Detroit, the rapper – real name Marshall Mathers – was often bullied in school before he dropped out altogether in Year 9.
But with his insane work ethic and "failure is not an option" mentality, Eminem became a worldwide sensation and won numerous Grammys. He is now worth $US250 ($388 million).
Oprah Winfrey overcame the odds to be one of the most successful TV personalities of all time.
The talk show host was born to unwed teenage parents, before being raised by her maternal grandmother until she was six. Living off welfare, she then endured a childhood filled with sexual abuse and trauma.
After cementing her feet in the media, Winfrey is now reportedly worth $US2.7 billion ($3.9 billion).
Before she was making hits and headlines in Hollywood and beyond, rapper Cardi B worked as a cashier at a supermarket before becoming a stripper from aged 19 to make ends meet.
Things were so dire for the future Grammy winner that she stayed in a challenging relationship with her then-boyfriend just so she'd have a roof over her head.
"There was two pitbulls in that house, and I had asthma," Cardi recalled to Vibe in 2016. "There was bedbugs too. On top of that, I felt like my ex-boyfriend was cheating on me, but it was like even if he was cheating on me, I still can't leave because where was I gonna go?"
Cardi B – real name Belcalis Almánzar – continued to strip until she was 23 when she focused her attention on music. In 2015, she appeared on the hit VH1 reality series Love & Hip Hop: New York before her rap career blew up.
In 2018, she released her debut single Bodak Yellow and now, aged 30, Cardi is worth a cool $US40 million ($124 million).
Transformers star Shia LaBeouf says he appreciates his success and $US30 million ($46 million) fortune that much more, given he grew up with nothing.
"My dad and my mum were both artists who never found an audience for their artwork," he told Parade in 2009. "And so I lived in poverty. Now that I'm not poor, I know that is what it was."
"Like Hemingway said, you can't write anything if you've never been shot at or been gorged by a bull, you know? So I look back at that stuff and I'm grateful. It's like scars. You become proud of them."
Singer-songwriter Jewel grew up in a farmhouse in Alsaka that didn't have indoor plumbing. To make ends meet, the budding artist – full name Jewel Kilcher – and her father used to sing together in bars and taverns.
Sadly, a then-teenaged Jewel found herself homeless in 1993. and living in her car.
"I was propositioned by a boss, and when I wouldn't have sex with him, he wouldn't give me my paycheck," she explained in the 2019 documentary Lost In America"I couldn't pay my rent that month and I got kicked out of where I was living. I was living in my car, thinking it would only last a couple of months before I could get another job – and then my car got stolen."
But her luck was soon to change when she was discovered by a talent manager in a coffee shop in San Diego.
The singer's 1995 debut album, Pieces of You, went platinum thanks to hits Who Will Save Your Soul and Foolish Games. Today, the 49-year-old is now worth a reported $US14 million ($22 million).
