Kelly accessorised her glamorous look with a black patterned bag that featured a silver strap and diamond earrings.

She opted for a heavy palette of makeup for the outing and added a pop of matte red to her lips.

DJ Fat Tony, 58, and his fiancé Stavros Agapiou, 32, have been engaged since October 2023 and are set to walk down the aisle in a lavish and star-studded London ceremony.

Kate Moss and Gemma Collins will reportedly act as bridesmaids while A-listers including Boy George,Davina McCall, David and Victoria Beckham, and Kylie Minogue are also slated to attend.  

Kelly’s outing comes after she shared a new snap of herself earlier in the week looking dramatically different, reigniting speculation that she’s had plastic surgery.

The star took to Instagram on Thursday to post a couple of glamorous sH๏τs after getting her hair and makeup done, with her face looking smoother and more chiselled than ever.

Captioning the pH๏τos, Kelly, who is the daughter of rock legend Ozzy and TV star Sharon Osbourne, revealed she’d been all glammed up for her plans to be cancelled last minute, lamenting: ‘Sat through glam only to find that my day had been cancelled. #alldressedupandnowheretogo’.

However, her followers were distracted by her visibly much slimmer and tauter appearance, pointing to her sharper jawline, voluptuous lips and lifted brows.

They raced to the comments to admit they could barely recognise the star and accused her of getting heavy cosmetic work done that had made her look as though she’d had a ‘full head transplant’.

They commented: ‘Is Kelly Osborne in the room with us?’; ‘WHO IS THAT?? Wft….’; ‘Gifted a new head for Christmas….’; ‘totally different head’.

 ‘Who’s face is that?’; ‘Full head transplant’; ‘Lots of money and a good plastic surgeon and we can all be this beautiful’.

‘Wow amazing what tons of plastic surgery, ozempic and money can do’; ‘Is this the same Kelly Osbourne or..’; ‘New face, who dis?’

‘Where is Kelly?’; ‘can’t imagine how many surgeries, fillers, botox injections, skin treatments, etc. were involved in this transformation. When you no longer look anything like yourself, what exactly did you accomplish?’

‘Teenage Kelly would not be happy about this’; ‘What in the millions dollars worth of plastic surgery is this’; ‘Is she AI?!’

Kelly has undergone many changes in her appearance over the years. In 2020, the she revealed that she had quietly undergone gastric sleeve surgery two years before, leading to a jaw-dropping 85lb weight loss.

She also previously admitted to having injections to change the shape of her face, and make her jaw look ‘skinnier,’ after suffering with TMJ (temporomandibular joint dysfunction).

It comes after Kelly’s fans voiced their dismay after she shared a new snap of herself looking dramatically different, with her face looking smoother and more chiselled than ever reigniting speculation that she’s had plastic surgery

Kelly’s new look was world’s away from how she used to look before with a rounder and more ‘natural’ looking face (pictured in 2013) 

However, her followers were distracted by her visibly much slimmer and tauter appearance, pointing to her sharper jawline, voluptuous lips and lifted brows (seen in 2012)

However, Kelly has repeatedly and furiously denied that she has had any cosmetic procedures besides Botox. 

Last year, she declared that she was a ‘huge fan’ of plastic surgery, but insisted that she was too scared to get anything done after seeing her mother go under the knife so many times.

She told People: ‘I am a huge fan of plastic surgery. What it does for people is amazing. It can change people’s lives and give them the confidence they’ve been lacking, and make people feel beautiful in the way they want to feel beautiful.

‘But I’ve never done anything but Botox. I’m too scared. I’ve always been in the camp of, if you think it’s broken, fix it. You don’t have to be stuck with a nose you hate for the rest of your life. So yes, I’m a huge fan.’

She explained the root of her fear, saying: ‘I watched my mum go through every recovery from everything she’s ever had done, and it looks awful’.

Sharon, 72, has undergone a range of procedures including a gastric band, full facelift, tummy tuck, an eyelift, breast implants, abdominoplasty and Botox. 

While she has branded her 2021 facelift the ‘worst thing she ever did’ after the procedure left her ‘looking like a cyclops’ and ‘Quasimodo’.

However, her mum Sharon previously admitted that she ‘needed to put weight back on’ after losing a shocking 42lbs on Ozempic (pictured in November 2023) 

Back in March last year, Sharon shocked the public after she made her return to UK reality TV on Celebrity Big Brother. 

The star couldn’t hide her weight loss on the show as she revealed doctors ‘can’t figure out’ why she hasn’t been able to gain weight back after she stopped using Ozempic months ago. 

‘The doctors can’t figure it out,’ she said. ‘But I think it’s just because I’m getting older and as you get older you lose weight anyway and shrink and shrivel off.’

Of why she decided to start receiving Ozempic injections, Sharon said ‘everyone was doing it’.
