It can feel like everyone you know is currently taking Mounjaro, and now another celebrity has joined the ranks of those praising the medication.

Presenter and comedian Rosie O'Donnell has opened up about her experiences with the jabs and the results she has achieved.

She joins the likes of Meghan Trainor, Scott Disick, comedian Amy Schumer and more, in expressing their love for the medication and for the benefits they say they've experienced.

It comes after a side-by-side study was carried out, to see which was better out of Mounjaro and Wegovy.

Many other celebrities are also known to be taking Ozempic, another form of the jab.

Rosie O'Donnell recently relocated to Ireland with her child, in the wake of Donald Trump getting into office again.

"OK so went shopping to but a comfy lounge wear outfit for my 22 hour flight to australia," she captioned the dressing room pic.

"I was undecided as I can't see myself in this new smaller body," she explained.

"Cam n Robin took this photo of me in the dressing room - I am shocked I'm a 12 - Mounjaro is a life saver," she finished with an emotional emoji.

She revealed in the comments that she has type 2 diabetes so has been taking Mounjaro to help treat her condition, but has been delighted with the results.

Rosie also said she had 'zero' side effects but believes the price should be lowered and expressed her gratitude that her insurance covers it because of her diabetes.

She also said in another comment she has been losing '2 pounds a month'.

Another added, "You look awesome – although your Beautiful soul shines through in ANY body."

Rosie previously revealed that she started taking Mounjaro back in 2022.

On TikTok she said: "I really stopped drinking five or six Diet Cokes a day. All I drink is water now, and I'm not eating sugar as much as I can."

"I can't believe this is me now!" she raved. "I am on Mounjaro for my diabetes, and one of the side effects is you lose weight," she explained on another TikTok back in March.

"But [the weight loss] is 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."

She also revealed she has lost around 50lbs over the last three years.

“I'm one of those people who's always had a weight issue and now that I'm a size large, instead of an XL or a 2XL, I find it shocking,” Rosie continued.

“I've been wearing elastic-waist pants for a very long time.”
