In a deeply personal and revealing moment captured via Instagram, comedian and actress Rosie O’Donnell confessed she’s still coming to terms with her leaner silhouette—now fitting into a size 12—for the first time in years. Her candid post, shared ahead of a long-haul flight to Australia, has sparked immediate buzz across social media and Reddit forums, where fans are both cheering her progress and applauding her honesty.
A Moment Frozen in the Dressing Room
O’Donnell recently posted a photo taken by actress friends Camryn Manheim and Robin Ruzan as she tried on lounge wear for her 22-hour flight to Australia. Clad in a fitted black athleisure set, she confessed:
“I am shocked I’m a 12 — #mounjaro is a lifesaver.”
The sentiment—surprised, grateful, still adjusting—captures the emotional undercurrent of her journey. She admitted that seeing herself in this “new smaller body” remains surreal.
The Journey Behind the Transformation
Mounjaro and Lifestyle Changes
O’Donnell has been on Mounjaro (a semaglutide-based diabetes medication) since early 2023, initially prescribed to manage her type 2 diabetes. A side effect—one she openly welcomes—is weight loss. On average, she’s shed one to two pounds a month, attributing much of this physical shift to the medication’s appetite-suppressing effects.
Her relocation from Los Angeles to Ireland in early 2025 also played a crucial role. Without a personal chef, Rosie began cooking for herself and her 12-year-old son, Clay, embracing homemade meals over others’ choices. The move brought emotional clarity and contributed to healthier habits.
Clothing Size Shift
Previously, O’Donnell was wearing XL or XXL sizes. Now, fitting into a large (size 12) feels surreal—a testament she hasn’t yet emotionally aligned with. She even acknowledged that shopping now requires adjustments: “I can’t see myself in this new smaller body.”

- Fellow celeb Kristin Chenoweth chimed in with “You look amazing!” following the news.
Reddit’s Real Talk
On Reddit, forums burst with multifaceted responses:
“Watching her accept her new normal is deeply human.”
“It’s not just the weight—it’s the adjustment to self that’s powerful.”
Others raised thoughtful concerns about medications like Mounjaro and the complex emotions tied to rapid physical changes.
