Who Is Sid Wilson? 5 Things to Know About Kelly Osbourne’s Ex-Fiancé – Hollywood Life

Sid Wilson is best known for his heavy metal career, but in recent years, his relationship with ex-fiancée Kelly Osbourne has taken center stage. The couple, who went public with their romance in 2022 after decades of friendship, became proud parents and got engaged on July 5, 2025 — the same day Kelly’s father, Ozzy Osbourne, gave his final performance in Birmingham, England. Later that month, the family mourned Ozzy’s passing at age 76.

Unfortunately, Sid and Kelly’s relationship didn’t stand the test of time. Multiple outlets reported in March 2026 that the duo had called it quits and ended their engagement.

Previously, Kelly opened up about the “biggest fight” she and Sid had, over naming their son.

“It’s the biggest fight me and my baby’s father have ever, ever, ever had, and probably ever, ever, will was over naming our son,” she told her parents, Ozzy and Sharon Osbourne, during a 2024 episode of “The Osbournes” podcast. “I wanted our son to have both of our last names, and he wouldn’t let me, and we had a huge fight. I feel that I was forced into doing something I didn’t want to do.” 

Kelly clarified, however, that she “loves” Sid’s name. “Don’t get me wrong. I love my baby’s name. He is a Sidney,” she acknowledged. “I don’t mind that he has his name Sid. I don’t mind that they have the same middle name.”  

The former Fashion Police presenter went on to explain the reason why she still wants to change their son’s name. 

“We both made our child, so they should have both of our last names,” she added. “Not one is more important than the other. … It was more about pleasing his family than it was about pleasing me, and I’m his partner.”
