Sharing the exciting discovery, Rosie sounded overjoyed in her post as she revealed the news.
In the caption, she said, “Ok, so went shopping to buy a comfy lounge wear outfit for my 22-hour flight to Australia.
“Was undecided as I can’t see myself in this new smaller body,” she went on.
Rosie added, “[My friends] took this photo of me in the dressing room — I am shocked I’m a 12 — #mounjaro is a life saver.”
Fans were quick to flock to the comments section to swoon over Rosie’s slim new look.
“Super impressive!!! You look wonderful,” said one person.
“Gosh, you look great! Wish I could get some monjaro,” added a second.
A third penned, “Rosie shrinking. Looking healthy and great.”
“You look great. Healthy. I hope you are feeling good,” echoed a fourth.
“You truly look beautiful at any size! 12 fits you well,” wrote a fifth.
While a sixth said, “If you’re feeling good, you’re looking great. As someone who’s been a fan since I was 12 (1996) you’ll always be beautiful to me.”
And a seventh added, “You look incredible! But what really matters is that you are still you.
“Brilliant, crazy funny, kind, decent and compassionate human. You are amazing and inspiring!”
Everything you need to know about fat jabs
Weight loss jabs are all the rage as studies and patient stories reveal they help people shed flab at almost unbelievable rates, as well as appearing to reduce the risk of serious diseases.
Wegovy – a modified version of type 2 diabetes drug Ozempic – and Mounjaro are the leading weight loss injections used in both the US and the UK.
How do they work?
The jabs work by suppressing your appetite, making you eat less so your body burns fat for energy instead and you lose weight.
They do this my mimicking a hormone called GLP-1, which signals to the brain when the stomach is full, so the drugs are officially called GLP-1 receptor agonists.
They slow down digestion and increase insulin production, lowering blood sugar, which is why they were first developed to treat type 2 diabetes in which patients’ sugar levels are too high.
Are there any risks?
Yes – side effects are common but most are relatively mild.
Around half of people taking the drug experience gut issues, including sickness, bloating, acid reflux, constipation and diarrhoea.
Dr Sarah Jarvis, GP and clinical consultant at patient.info, said: “One of the more uncommon side effects is severe acute pancreatitis, which is extremely painful and happens to one in 500 people.”
Other uncommon side effects include altered taste, kidney problems, allergic reactions, gallbladder problems and hypoglycemia.
Evidence has so far been inconclusive about whether the injections are damaging to patients’ mental health.
Figures obtained by The Sun show that, up to January 2025, 85 patient deaths in the UK were suspected to be linked to the medicines
Rosie revealed she was using mounjaro back in January 2023.
She revealed that she was starting her weight loss transformation in a TikTok video.
Rosie then shared an update this March, revealing how she had “lost more weight”.
After moving to Ireland, she said, “I’ve lost more weight.
“I am on Mounjaro for my diabetes and one of the side effects is you lose weight.
“But it’s also because I had a chef for over two years in Los Angeles and I don’t have a chef now. It’s me cooking for Clay and me.”
