Kelly Osbourne rang in her milestone 40th birthday with a surprise for fans: a series of unrecognizable childhood photos that showcased a side of her rarely seen. As the daughter of rock legend Ozzy Osbourne and former X Factor judge Sharon Osbourne, Kelly has lived her entire life in the public eye—but the throwback images she shared on Instagram, featuring six dramatically different hairstyles, proved that her flair for bold self-expression began long before fame. Fresh-faced, mischievous, and already experimenting with color and cuts, the photos confirmed what longtime followers know well: Kelly has always been a style chameleon.
Rising to prominence through The Osbournes and later solidifying her pop-culture presence through music, fashion, and reality TV, Kelly has continually embraced reinvention. But with constant transformation comes constant scrutiny—and her recent physical changes drew widespread speculation. Kelly addressed the rumors head-on, firmly denying that she used Ozempic to lose weight, despite her mother Sharon openly acknowledging that she had taken the drug.
Kelly, who shares her son Sidney with partner Sid Wilson of Slipknot, revealed that the true catalyst for her transformation was health-related. During her pregnancy, she developed gestational diabetes, leaving her at heightened risk of developing the condition later in life. After giving birth, she committed to a major lifestyle overhaul. “I cut out sugar and carbohydrates and I rapidly lost weight,” she explained, adding that she also turned to body-toning treatments to tighten her stomach and sculpt her face after pregnancy changed her skin’s elasticity.
Though she personally avoided Ozempic, Kelly admitted that her perspective on the medication has softened. Meeting someone who credited the drug with removing the “mental obsession with food” shifted her thinking and opened her mind to the idea that weight-loss tools can have psychological benefits as well. “If there’s a medication out there that can help people lose weight then what’s so bad about it?” she now says.
Candid, evolving, and unafraid to speak openly—Kelly Osbourne remains firmly rooted in the Osbourne family tradition of honesty, resilience, and reinvention.
