Kelly Osbourne recently celebrated her four-year anniversary with her partner, Sid Wilson of the band Slipknot.
The reality star and daughter of rock legend Ozzy Osbourne shared the milestone on social media, reflecting on their journey from longtime friends to a committed couple.
Kelly often describes Sid as her "best friend" and "soulmate," noting that their deep bond grew from over two decades of friendship before they officially began dating in January 2022.
The anniversary follows a major family milestone from last summer. In July 2025, Sid proposed to Kelly backstage during Ozzy Osbourne’s final performance with Black Sabbath in Birmingham.
The emotional moment went viral after Kelly shared a video of Sid dropping to one knee. In true rock-and-roll fashion, Ozzy jokingly told Sid to "f*** off" before the family erupted in cheers.
The couple shares a son, Sidney, who was born in late 2022 and has become a central part of their lives.
Kelly and Sid first met in 1999 at the Ozzfest music festival but remained platonic for many years.
Their romantic relationship only blossomed later in life, a transition that Kelly has admitted surprised her.
She frequently posts about how much she values Sid’s support, especially as they navigate parenthood together.
Their recent red carpet appearances and public declarations of love show a couple that remains very much in the honeymoon phase despite their long history.
Fans of both the Osbourne and Slipknot families have embraced the pairing, often calling them a "rock and roll power couple."
As they celebrate four years together, rumors continue to swirl about their upcoming wedding plans, though the couple has not yet announced a specific date.
For now, Kelly and Sid appear focused on enjoying their life with their son and supporting each other's busy professional schedules.
Their anniversary serves as a testament to the strength of a relationship built on a foundation of long-term trust.
