Comedian and TV icon Rosie O’Donnell has left fans speechless after revealing her dramatic physical transformation, attributing her weight loss to the diabetes drug Mounjaro and a more hands-on lifestyle since relocating to Ireland.
The 63-year-old recently posted a striking photo on Instagram, showing her slimmer figure while performing stand-up. With the caption, “I can’t believe this is me now #mounjaro #weightloss #bodydismorphia,” O’Donnell opened up about her evolving relationship with her body—and the help of medication.

A Lifestyle Change That Made a Difference
Back in March 2025, O’Donnell posted a TikTok explaining how moving to Ireland with her child, Clay, has deeply influenced her health. Without the personal chef she had in Los Angeles, Rosie now cooks her own meals—and that shift has made a noticeable impact.
“I’ve lost more weight here,” she shared. “I am on Mounjaro for my diabetes, and one of the side effects is that you lose weight. But it’s also because… I’m cooking for Clay and me.”
The View alum admitted she’s still adjusting to the change, candidly revealing that she now wears a size large instead of XL or XXL.
“I find it completely shocking,” she said. “I really do.”

What Is Mounjaro?
Mounjaro (tirzepatide) is an FDA-approved injection used primarily to treat type 2 diabetes. One of its well-known side effects is weight loss, making it a popular off-label choice for people aiming to shed pounds. However, the drug is prescribed alongside dietary changes and regular exercise.
While a similar brand, Zepbound, is specifically approved for weight loss, Mounjaro currently has no generic alternative. It’s administered as a weekly injection, and its popularity has surged among public figures managing diabetes and obesity.
