Kelly Osbourne and Fiance Sid Wilson Split as She Continues to Struggle Following Ozzy’s Death

Kelly Osbourne and fiancé Sid Wilson have broken off their engagement.

“Kelly and Sid have decided to call off their engagement,” a source told the Daily Mail on Monday, March 23. “Kelly has been struggling following the loss of her father. The grieving process has been incredibly difficult, and she’s been doing everything she can to cope.”

The source continued, “In truth, she and Sid have been facing challenges in their relationship for some time, and things were not as they appeared. They tried to make it work, particularly for the sake of their child, but ultimately decided that separating is the best path forward. Kelly has endured a great deal over the past year. Despite everything, she remains sober and is now focusing on herself and her role as a mother moving ahead.”

Sid, 49, proposed to Kelly, 41, at her father Ozzy Osbourne’s final concert in July 2025. Ozzy died at the age of 76 just a little over two weeks later.

Kelly has been open about struggling with her father’s death since his passing and she’s faced harsh criticism about her looks online. After appearing at the BRIT Awards alongside her mother, Sharon Osbourne, earlier this month, she addressed the situation and possibly hinted at relationship troubles with Sid.

“There is a special kind of cruelty in hurting someone who is already going through something deeply painful,” Kelly wrote in her Instagram Story. “Being kicked while I’m down, having my pain questioned, my struggles turned into gossip, and being abandoned when I need love and support the most – none of this reflects strength. It only shows a lack of compassion and character.”

She concluded by adding, “I am going through one of the hardest periods of my life. I shouldn’t have to defend myself, but I also won’t allow myself to be dehumanised like this.”

Sid and Kelly share one son, Sidney, 3.
