Is Kelly Osbourne Sick? The Heartbreaking Reason Sharon's Daughter Can't Eat in 2026

Kelly Osbourne has lashed out at online trolls questioning if she is sick amid her stark weight loss, revealing grief over her father Ozzy Osbourne's death last year has left her unable to eat properly. The 41-year-old TV personality and singer made the plea after facing cruel comments following her appearance at the 2026 BRIT Awards in Manchester on Feb. 28, where she accepted a Lifetime Achievement Award on behalf of the late Black Sabbath frontman alongside her mother Sharon.

Ozzy died on July 22, 2025 at age 76 from cardiac arrest linked to coronary artery disease and Parkinson's, plunging the family into mourning. Kelly first aired her frustration in December 2025 in a now-deleted Instagram video, responding to detractors who had written comments such as 'Are you ill?' and 'Get off Ozempic, you don't look right.' She said her father had just died, that she was doing the best she could and that her family was the only thing keeping her going, before telling critics to 'f--- off'. Sharon swiftly defended her, telling Piers Morgan that her daughter 'can't eat right now' following the loss of her father.

Kelly Osbourne's Long Battle with Weight Scrutiny

Kelly's body has been public property since she first appeared as a teenager on The Osbournes more than 20 years ago, a show that laid bare the family's chaos. Early in her career, an agency executive summoned her for what she later described as a brutal lecture, telling her she was 'too fat for TV' and could be a film star if she lost weight, as she recalled on a 2024 episode of The Osbournes Podcast. The experience lingered, fuelling a cycle of addiction, self-loathing and intense scrutiny that no level of fame could shield her from.

Fast forward to 2018, and she opted for gastric sleeve surgery, slashing 85 pounds by having part of her stomach removed to curb hunger. 'I had surgery; I don't give a f--- what anyone has to say,' she told the Hollywood Raw podcast hosts in 2020. 'It is the best thing I have ever done.' She paired it with workouts and cleaner eating, crediting it for also dulling addiction cravings by nixing a hormone tied to emotional binging.

Even that triumph came with barbs, particularly during her pregnancy with her son Sidney in 2022 with DJ Sid Wilson of Slipknot. She gained 100lb, avoided the spotlight to escape cruel taunts and battled gestational diabetes as her body struggled to process sugar.

Post-baby, she pushed hard, admitting on Scheana Shay's podcast in 2023 that she had taken weight loss 'a little bit too far' but pulled back. Rumours swirled of Ozempic use, which she flatly denied in a 2024 Extra interview.

'I know everybody thinks I took Ozempic. I did not take Ozempic,' she said at the time. Her tune softened later, praising the drug on her family podcast after hearing how it freed users from food obsessions, letting them tackle deeper issues in therapy.

She has since turned to non-invasive fixes like EMFACE and EMSCULPT for stretch marks and saggy skin, plus jaw injections that sharpened her face. At a wellness summit in May 2025, she spoke candidly. Despite describing herself as a 'drug addict, an alcoholic ... a complete mess', she said the fat-shaming cut deepest.

She recalled people saying, 'You're so pretty. Why don't you just lose a little bit of weight and then you'll be the total package.' A shift in mindset, she said, ultimately changed everything.

Facing Trolls After Ozzy's Death and BRIT Awards Spotlight

The BRITs red carpet reignited the firestorm. Kelly drew attention in a velvet corset gown topped with a feathered bolero, her blonde bob freshly cropped and golden, with necklaces paying tribute to her father through an 'O' pendant. Photographs prompted the usual vitriol, with one online critic describing her as a 'dead body' heading to join Ozzy soon.

She responded on Instagram Stories, writing that there is 'a special kind of cruelty in harming someone who is clearly going through something.' She said critics were 'kicking me while I'm down, doubting my pain, spreading my struggles as gossip and turning your back when I need support and love most.'

'None of it proves strength; it only reveals a profound absence of compassion and character,' she added. Describing it as the hardest period of her life, she said she should not have to defend herself but would not allow herself to be dehumanised in such a way.

On stage, emotion cracked through as Sharon said she was 'honored' to collect the award, with Kelly adding a simple 'Thank you for loving my father as much as we do.' Backstage at the Grammys in February, she admitted, 'It's the hardest thing I've ever been through... I'm not doing so great.'

The toll is visible in viral photographs showing her 'giant' hands against a notably thinned frame, prompting health concerns she attributes entirely to grief rather than drugs. Sharon's defence holds: Kelly is not hiding illness, only experiencing raw loss. Critics preying on her pain reveal their own cruelty, while she leans on her family amid intense scrutiny. It is little wonder she reacted – who could not?
