Rosie O’Donnell can’t even believe her own transformation.

The ex-“View” co-host recently posted a photo showcasing her significant weight loss attributed to Mounjaro, over two years after disclosing her use of the type 2 diabetes medication.

“i cant believe this is me now,” the comedian captioned a slimmed-down photo of herself on Instagram Friday.

The snap appeared to show O’Donnell, 63, onstage as she was seen holding a microphone.

In January 2023, the “A League of Their Own” actress discussed her Mounjaro journey, having been prescribed the appetite suppressant a couple of months earlier as part of her diabetes management plan.

“Christmas, I stopped drinking anything except water,” she said at the time, revealing she had already shed 10 pounds.

“I really stopped drinking like five or six Diet Cokes a day,” she added. “All I drink is water now. And I’m not eating sugar as much as I can.”

O’Donnell gave an update on her health journey in March after moving to Ireland with her child Clay following President Trump’s election.

“I’ve lost more weight here,” the former talk show host said in a TikTok video.

While she mostly credited Mounjaro for her physical transformation, she also revealed another major lifestyle change.

“I don’t have a chef now. It’s me cooking for Clay and me,” O’Donnell said.

The “Harriet the Spy” actress admitted she’s “always had a weight issue” as she discussed shopping for new clothes at a boutique in Dublin.

“Being a size large now, instead of an XL or XXL, is something I find astonishing,” O’Donnell admitted, noting she had been in “elastic pants” for several years before.

But she said she feels “healthier” overall and has been “sleeping better.”

The “Rosie O’Donnell Show” alum been open about her weight struggles throughout her career.

After suffering a heart attack in 2012, O’Donnell underwent vertical sleeve gastric surgery the following year.

“That surgery changed my life,” she told People in 2015, revealing she dropped from 240 pounds down to 176.
