Kelly Osbourne marks a personal milestone backstage

Kelly Osbourne and Slipknot member Sid Wilson are engaged.

The proposal took place on July 5, 2025, backstage at Villa Park in Birmingham during Ozzy Osbourne’s final performance with Black Sabbath.

The engagement was confirmed by Osbourne in a post on Instagram, where she shared a short video of the proposal with the caption, “Oh and this happened yesterday!” The moment appeared to take place backstage and included family members celebrating.

Osbourne, 40, and Wilson, 48, have known each other since 1999 and began dating in early 2022. They have one child together, born later that same year.

Ozzy Osbourne, 76, returned to the stage for a farewell performance marking the close of his career with the band he co-founded in 1968. The engagement took place shortly after the concert, reportedly with his involvement and support.

The timing of the proposal has drawn attention due to its connection to a major milestone in the Osbourne family's public and musical history.

No additional details about future plans have been shared by the couple.
