SHE may be just 39, but recent photos of Kelly Osbourne have left even her most loyal fans stunned.
Despite the daughter of Ozzy and Sharon Osbourne having changed her appearance on countless occasions, fans of the reality TV star have raised concerns after she shared pics in a glam gown.
Posing next to Nicky Hilton, the singer wowed fans in a gorgeous off-the-shoulder white gown decked out with sparkly gems, which she had paired with a nude lippy and bright eye shadow.
''Feeling rather feminine!'' Kelly told her 2.7million followers on Instagram.
However, the post soon garnered attention from concerned fans who felt anxious about her appearance, with dozens saying she had become "way too skinny".
One social media user wrote: ''Am I the only one that finds this alarming?
''Girl you are taking the weight loss too far… surprising you feel feminine when you quite literally lost all of your curves… all bodies are beautiful but it is sad you need to be emaciated to feel like you can meet today’s beauty standards.''
In their eyes, not only had the star shed too much, but the weight loss had also aged her naturally stunning looks, as some said she ''looks old''.
The mum-of-one has always vehemently denied using the popular drug.
However, her most recent makeover is just one of many in the long line of transformations to her body - and Kelly has had to defend herself on multiple occasions.
Julia Hartley-Brewer slams government plan for NHS to offer free 'fat jabs' to tackle obesity crisis
She was just a teenager when she first appeared on our TV screens on the family's reality show The Osbournes, sporting jet black hair, a hot pink moment, or a bright red hairdo.
But despite being just 17, Kelly - who was dubbed ''wickedly funny and brutally honest'' by Rolling Stone - was already being exposed to brutal headlines about her weight.
The young girl was aware of how trolls saw her and bravely told the publication ''a lot of people think I’m really fat”.
In 2022, when chatting about her life with Jada Pinkett Smith on Red Table Talk, Kelly confessed that at one point it got so bad, she had voices in her head saying, "You’re fat, you’re ugly, you’re not good enough, no one likes you, you don’t deserve this, people only like you because of who your parents are".
The never-ending public criticism led Kelly to develop an addiction to painkillers after getting ''a really bad case of tonsillitis'' - which at one point saw the teenager pop in 50 pills a day.
But after managing to kick the drug addiction aside, the reality TV star realised she had ''replaced the drugs with food''.
She admitted: "I just got fatter and fatter... I'm an emotional eater."
He gave me a whole speech about how I was too fat for TV and I needed to lose weight, and that if I lost weight, I would look better
Kelly Osbourneon being cast in Freaky Friday
By now, the binge-eating and the extra pounds had changed her appearance - one she would go on to work so hard on altering in the following years.
After being cast in 2003's Freaky Friday as Maddie, opposite Lindsay Lohan, the aspiring actress claimed she was "pulled into" an agency head's office to discuss her weight.
Kelly said in an episode of the family's podcast : "He gave me a whole speech about how I was too fat for TV and I needed to lose weight, and that if I lost weight, I would look better.
"He was just saying, 'You're not a movie star, but you could be one if you lost weight'."
Kelly admitted that it was the "most insulting f*cking" thing.
After showing off her best dancing skills on Dancing With The Stars, where she placed third, Kelly underwent a dramatic weight loss of 20lbs, as a part of intense cardio sessions and a new diet.
She revealed: "I understand that being judged by others comes with the territory, but it broke my heart and ruined my self-esteem.
''It sets you up to hate yourself in a huge way. I was so angry about the things people said about me.”
However, it wasn't long before the pounds started to pile back on - and Kelly was really struggling with it.
She added: "I thought, 'Kelly, you've come this far, let's see what you can really do!’ I would look at myself and think, ‘Ugh!' To get to the gym, when you already don't like yourself, is really hard."
2018 - Gastric sleeve & going vegan
Fast-forward to 2018 and Kelly hit headlines after going under the knife for a gastric sleeve - which is a “bariatric surgery procedure” that “removes a large portion of your stomach, leaving behind a narrow ‘sleeve''', according to .
The star, who dropped a staggering six stone, has since described it as being “the best thing” she'd ever done and has been very vocal about her experience, telling fans it's far from a “quick fix” and requires a lifestyle change.
The mum-of-one said on The Hollywood Raw podcast in 2020: “All it does is move you in the right direction."
Kelly told the in 2019: “Once I learned how to work out right and eat right, it’s one of those things that you just have to commit to a life change rather than being on a diet."
In one post, she wrote: “I really miss eating cheese so today I tried ‘vegan shell pasta and creamy sauce’ aka Mac & cheese… you can not tell the difference.”
Another post said: “I used to think being a vegan was boring. Now I have more fun with food now than I ever have before.”

2021 - Secret surgery rumours
Kelly has always been very open about the work she has had done - however, in 2021 she had to shut down ''stupid rumours'' about plastic surgery following a chiseled face and brand-new jawline.
The star, whose fat underneath the cheekbones had seemingly vanished in thin air, said: ''I just want to bring up a topic that you guys are all talking about because I’m always really honest and really upfront about what I’ve done to my body and who I am.
''And I have not done plastic surgery.
"I’ve never done anything to my face other than a couple of injections in my lip, in my jaw, and in my forehead. I do not lie, but thank you for the compliment.''
Sharing a glam snap of two lilac space buns and a sharp bone structure, Kelly captioned the post: ''Let’s squash these stupid rumors!!! Can’t you just be happy for me?
"One thing I did that changed my face... one of the things they did to stop it was they gave me injections in my jaw.
"It kinda made my jaw look skinnier.
"That's when people started to notice that I had really lost weight because it changed the shape of everything.
''I found out It’s called buckle fat. It changed everything on my face! How the f*** did I not know about this sooner?''
She told : "I just have to clarify, I've never taken Ozempic. I don't know what Ozempic does to you other than what I saw it do to my Mum.
"I think it is a miracle drug in the right hands.
"But for some reason society is trying to paint it out to be a bad thing.
"And I don't understand why.
"If you need to lose some weight who cares how you do it, as long as you're doing it in a healthy way."
There are a million ways to lose weight, why not do it through something that isn’t as boring as working out?

However, whilst she may not be taking the drug herself, the 39-year-old incited fury after admitting she thinks the once-weekly semaglutide injection is “amazing” and hit out at people who criticise others for using the popular drug.
The singer told : “I think it’s amazing.
“There are a million ways to lose weight, why not do it through something that isn’t as boring as working out?”
Although critics have urged people to steer clear of the drug for its off-label weight loss side effects, Kelly insisted that those who scrutinise Ozempic simply don't have the means to buy it.
She said: “And the people who hate on it the most are the people who are secretly doing it, or pissed off that they can’t afford it.
''Unfortunately, right now it’s something that is very expensive but it eventually won’t be because it actually works.”
The comments sparked backlash on social media, with one X user writing: “Rich people have easy access to healthy food options, personal trainers and chefs but they choose to take Ozempic that’s not meant for them and causing shortages for those who truly need them.''
