Sid Wilson proposed to Kelly Osbourne backstage at Ozzy Osbourne’s final Black Sabbath concert in Birmingham in July 2025 - months before Ozzy died. The engagement lasted less than a year. On August 4, Osbourne posted a series of messages on Instagram that brought the private aftermath into public view.

The Engagement That Began in Grief

Ozzy Osbourne died in July 2025. The engagement had happened at his farewell concert - a moment his family described as one of the last meaningful nights they had with him. Osbourne and Wilson had known each other for 23 years through the music world, and they share a 3-year-old son, Sidney. People and the Daily Mail reported in March that the engagement had ended, with sources describing the split as mutual and citing the weight of Osbourne’s grief as a central factor. Neither Osbourne nor Wilson made any public statement at the time.

What Changed This Week

On August 4, Osbourne posted multiple Instagram Stories that were widely read as a public response to a private conflict. “Strange how the loudest defense of the guilty is rarely innocence,” she wrote in one post, per People. “It’s distraction. When the mask slips, they don’t face the mirror - they throw it at someone else.” A second post referenced mirrors and bad luck. A third said she “always takes accountability.” She also posted directly about belongings, parenting, and support - specifics that suggested an active dispute rather than a general reflection.

People reported she is “not happy” and that the private situation had escalated. Wilson has not responded publicly.

What the Documented Record Shows

The engagement began at her father’s final performance and ended privately months later. The son is 3. The posts on August 4 are the first time either party has indicated publicly that the split involved conflict rather than mutual grief. No legal proceedings have been reported. The situation is developing.
