Kelly Osbourne Engaged to Slipknot's Sid Wilson

Kelly Osbourne got more than just a memorable night at her father's final Black Sabbath concert — she got a surprise proposal from her longtime partner, Sid Wilson.

Kelly Osbourne, 40, is officially engaged to Slipknot DJ Sid Wilson, 48. The proposal took place Saturday, July 5, 2025, during Ozzy Osbourne's farewell performance with Black Sabbath at Villa Park in Birmingham, England.

In a video posted to Instagram, Wilson can be seen turning to Kelly backstage saying, "Kelly, you know I love you more than anything in the world." Before he could finish, her father, Ozzy Osbourne, 76, humorously shouted "[expletive] off, you're not marrying my daughter," prompting laughter from the crowd and the couple.

Unfazed, Wilson continued, "Nothing would make me happier than to spend the rest of my life with you. So, in front of your family and all of our friends, Kelly, will you marry me?"

Kelly, clearly stunned, looked around before nodding "yes" and embracing Wilson as family and friends, including her mother Sharon Osbourne and brother Jack Osbourne, applauded the emotional moment.

The couple's relationship has deep roots. They first met in 1999 when Wilson's band Slipknot toured with Ozzfest, the music festival created by Ozzy and Sharon Osbourne. Though they remained friends for years, their relationship turned romantic in January 2022.

Just a few months later, in May 2022, the couple announced they were expecting their first child. Since then, they've kept their personal life relatively private while occasionally sharing family milestones with fans.
