Kelly Osbourne, Sid Wilson Split: Sharon Allegedly 'Devastated' as Daughter's Family Is 'Broken Apart'

Kelly Osbourne and Slipknot star Sid Wilson have split after seven months of engagement, leaving her mother Sharon Osbourne heartbroken over the fracturing of their young family. The couple, parents to three-year-old son Sidney, quietly ended their relationship over a month ago, sources close to the family say. This comes amid fresh revelations that Sharon is struggling alone with grief and estate matters following Ozzy Osbourne's death last summer.

Kelly, 41, and Sid, 49, seemed solidly on track until recently. They welcomed Sidney in late 2022 after a long friendship that blossomed into romance – the pair first met back in 1999 when Slipknot toured Ozzfest, Ozzy and Sharon's festival. Then came the proposal on 5 July 2025, backstage at Ozzy's emotional final Black Sabbath gig in Birmingham, mere weeks before the Prince of Darkness suffered fatal cardiac arrest on 22 July at age 76.

Heartache Over Split

Word of the breakup surfaced publicly around late March 2026, but insiders insist it happened quietly earlier. A source speaking to Star magazine paints a picture of Sharon, 73, as 'devastated,' hating to witness 'their little family broken apart.' 'Of course, she has Kelly's back and is supporting her all the way, and she's glad to be able to be there for her daughter, but it's very sad,' the source confides.

That joy from the engagement – a rare bright spot amid Ozzy's farewell – has curdled into quiet resignation. Sharon 'was so happy when he proposed to Kelly at Ozzy's final show. It was at least one piece of good news to hang on to.' Now Kelly is firm, with no reconciliation planned, leaving her mother to bite her tongue and hold back.

The Osbourne saga is raw – celebrity excess tangled with real human mess. Sharon rallied the family after Ozzy's passing, yet Kelly's absence hits harder. 'Kelly isn't able to be there in the same way either right now because she's dealing with the breakup and all that comes with it,' the source says. Sharon understands, yet her own grief lingers, compounded by the solo management of Ozzy's sprawling estate.

Overwhelming barely covers it. Friends note, 'She really needs help, but she's too proud to accept it from anyone outside the family, and that's making this all even harder.' Their hands are tied when the matriarch refuses to budge.

The weight of the Osbournes' turmoil is palpable. Their chaos has always played out publicly through reality TV, yet this moment feels heavier, more private. Ozzy's death certificate cites cardiac arrest with underlying coronary disease and Parkinson's, a harsh finale to decades of rock 'n' roll excess.

The Birmingham gig was meant as triumph, Sid dropping to one knee amid family cheers, Ozzy even offering a gruff blessing on video. Yet grief is a thief; reports suggest Kelly's post-loss period has been 'incredibly difficult,' straining her relationship with Sid, mutual as the split appears.

Strain on Family as Split Unfolds

Adding the toddler into the mix makes the situation even more wrenching. Little Sidney, born November 2022, was meant to anchor what had been billed as a soulmate union – Kelly once described Sid as her 'best friend' after 23 years together. Sources hint at a persistent 'hot-and-cold' dynamic between the couple, yet co-parenting remains the stated priority. Details on custody are scarce, but Sharon's visible dismay highlights the ripple effect: one child stretched thin and another grandchild shuffled between ex-partners.

Sharon's juggling act verges on heroic folly. Estate wrangles rest squarely on her shoulders, with no full support from siblings. Jack and Aimee hover, while Kelly remains sidelined by heartbreak. It is a tableau of frayed bonds, where help flows one way yet leaves gaps elsewhere.

Those close to her voice concern, noting she is still very much grappling with her own grief and too stubborn to accept aid. In celebrity circles, where splits often erupt in tabloid spectacle, this one remains subdued – no Instagram blasts, only whispers. That restraint only deepens the pathos of a family icon alone at the helm.

The Osbournes thrived on spectacle, but loss strips the varnish. Sid's Slipknot mask – literal and figurative – fades into co-parent footnotes. Kelly, ever resilient, faces this pivot head-on, while Sharon remains the rock cracking under pressure, hoping for fixes that cannot hold.
