Television icon and comedian Rosie O’Donnell has made a high-profile return to the public spotlight, pairing a deeply personal revelation about her physical health with an upcoming return to late-night hosting. In a candid interview published by People, the 64-year-old former daytime talk show host credited the GLP-1 receptor agonist Mounjaro with “saving” her life, shedding light on a decades-long struggle with weight, grief, and the intense scrutiny of the entertainment industry.
At the same time, O’Donnell is preparing to step back behind the talk show desk. Appearing on NBC’s Late Night with Seth Meyers, she confirmed she will serve as a guest host on ABC’s Jimmy Kimmel Live! for the week of August 17, promising to maintain the show’s sharp-witted political commentary and signature jabs at Donald Trump during Kimmel’s summer hiatus.
A Lifesaving Intervention Rooted in Childhood Trauma
O’Donnell’s emotional testimonial links her weight journey directly to profound childhood grief. She revealed that her struggles with obesity began in 1973 following the death of her mother, Roseann O’Donnell. In the wake of the tragedy, O’Donnell recalled her father giving his five children a single $100 bill to handle the family’s grocery shopping at Foodtown. Without parental guidance, the siblings relied on processed, non-nutritious items like Entenmann’s baked goods and Cap’n Crunch cereal.
“We would always say, ‘Subtotal please,’ and when it got near $100, we’d put back the chicken and the hamburger meat,” O’Donnell shared, describing how the entire family gained weight while navigating severe emotional trauma.
Decades later, O’Donnell turned to Mounjaro. Over the course of three years, she has lost a steady one to two pounds per month, a gradual pace she credits with transforming her health. “Mounjaro saved my life,” she declared. She expressed such gratitude for the medication that she offered to film commercials for the drug for free, provided the manufacturer would lower its retail price for regular consumers. “When I see people struggling with obesity, I want to say I know the shame that we carry and the humiliation that is dealt to people who are overweight,” she added.
The Anxiety of the Late-Night Spotlight
O’Donnell also reflected on the immense physical pressures faced by women in television, particularly in the late-night format. She confessed that during her early career guest appearances, such as on The Pat Sajak Show, her performance was overshadowed by self-doubt regarding her appearance.
“My biggest concern wasn’t my set, it was, did I look fat?” O’Donnell admitted, noting she would obsess over how she looked in a blazer even before she was clinically overweight. Today, however, she reports feeling “much healthier and more powerful” in her own body, a shift that coincides with her return to the late-night arena.
A Divided Celebrity Landscape on GLP-1 Drugs
While O’Donnell’s experience with Mounjaro has been overwhelmingly positive, her advocacy highlights a growing divide among public figures regarding GLP-1 medications. The cultural conversation surrounding these drugs has intensified as other celebrities report severe adverse reactions.
In June, actress Mayim Bialik published a detailed essay describing her highly negative experience on a GLP-1 drug, which she took to address unspecified health issues. The Big Bang Theory alum reported suffering from “explosive, uncontrollable diarrhea,” severe cramping, bloating, full-body aches, and sneezing attacks whenever she attempted to eat or drink.
Similarly, actress Jenny Mollen recently detailed a medical emergency on Kelly Ripa’s podcast. Mollen claimed that while “microdosing” a GLP-1 alongside other peptides to treat autoimmune and hyperthyroid conditions, she suffered massive hemorrhaging. The episode culminated in her fainting multiple times and being rushed to the hospital. While Mollen acknowledged the bleeding could have been related to perimenopause or the erratic process of stopping and restarting the drug, the incident underscored the potential risks and lack of standardized regulation surrounding off-label usage.
Returning to the Desk on Jimmy Kimmel Live!
Despite the medical debates, O’Donnell’s immediate focus is her upcoming stint on Jimmy Kimmel Live!. During her conversation with Seth Meyers, she expressed excitement about stepping into the hosting role, framing it as an opportunity to keep Kimmel’s politically charged comedic spirit alive during his summer break.
Kimmel officially announced O’Donnell as part of his summer guest-host rotation last month. Given O’Donnell’s history as a prominent, vocal critic of Donald Trump, both she and Meyers joked about the inevitable political material her hosting week will generate. “We’re gonna get through it,” Meyers laughed, while O’Donnell promised she has no intention of holding back her signature political commentary when she takes the stage on August 17.
