Sidney is the son of television personality Kelly Osbourne and Slipknot musician Sid Wilson. The couple welcomed him in late 2022, and Kelly’s mother, Sharon Osbourne, publicly identified him by name in January 2023. Kelly has also made clear that she wants to decide what details about her son are shared publicly.
Who is Kelly Osbourne’s son Sidney?
Sidney is Kelly Osbourne and Sid Wilson’s son. Kelly announced her pregnancy in 2022; the family’s public confirmation of his birth came later that year, and Sharon Osbourne shared his name in January 2023. Sky News reported the name and the family’s response on January 5, 2023.
Why has Kelly kept details about Sidney private?
After Sharon disclosed Sidney’s name, Kelly objected to other people sharing information about her newborn before she was ready. In an Instagram Story quoted by Sky News, she said: “I am not ready to share him with the world. It is no one’s place but mine to share information on my baby.” Her statement set a clear boundary around public disclosures; it does not provide a reason to infer details about Sidney’s private life.
What is Sidney’s surname?
In February 2024, Kelly discussed the subject on The Osbournes Podcast. ABC News reported that she wanted Sidney to have both parents’ surnames and said: “We are going to legally change our son’s name to have both of our last names.” That is evidence of her stated plan at the time, not confirmation that a legal name change was completed. The sources cited here do not establish Sidney’s current legal surname.

What has been reported about Kelly and Sid Wilson since?
Wilson proposed to Kelly backstage at Ozzy Osbourne’s final Black Sabbath show in July 2025, and contemporaneous coverage reported that she accepted. People covered the proposal.
A 2026 NME report said that Kelly and Wilson later separated. That reported relationship status does not establish anything about Sidney’s custody, care, or home life; no such details are stated in the sources cited here.

What is known—and what is not
The public record supports a limited account: Sidney is Kelly Osbourne and Sid Wilson’s son, his birth was publicly confirmed in late 2022, and Sharon Osbourne gave his name in January 2023. Kelly has spoken about privacy and her intention to include both parents’ surnames. Beyond those disclosures, a fuller portrait would require details the family has not chosen to share publicly.
