Kelly Osbourne and her baby’s father, Sid Wilson, got engaged backstage at her dad Ozzy Osbourne’s final Black Sabbath concert over the weekend.

The Slipknot DJ popped the question to the singer and TV personality at Birmingham, England’s Villa Park on Saturday in a moment shared on social media by his betrothed.

“Kelly, you know I love you more than anything in the world,” he said before her potty-mouthed father interjected: “F–k off, you’re not marrying my daughter.”

Wilson went on to extol Kelly’s virtues as he made his marital intentions known.

“Nothing would make me happier than to spend the rest of my life with you,” the 48-year-old said. “So, in front of your family and all of our friends, Kelly, will you marry me?”

Kelly, 40, appeared shocked by the proposal. She nodded yes before embracing Wilson as everyone cheered them on. Her mother, Sharon Osbourne, and brother Jack were also present.

The couple, who share 2-year-old son Sidney, went public with their romance on Valentine’s Day 2022.

“After 23 years of friendship I can’t believe where we have ended up,” Kelly captioned an Instagram snapshot of the pair kissing. “You are my best friend, my soulmate and I am so deeply in love with you Sidney George Wilson.”

Her father, has been diagnosed with Parkinson’s disease, announced in 2023 that he is retiring from live performances after more than 50 years.

Ozzy, 76, original Black Sabbath bassist Geezer Butler, drummer Bill Ward and guitarist Tony Iommi reunited for the first time in two decades at the “Back to the Beginning” concert, which was livestreamed in the U.K.

The 10-hour show, hosted by Jason Momoa, also featured performances from Metallica, Guns N’ Roses, Steven Tyler and Jack Black, among others.

During his set, the British rocker sang hits such as “Crazy Train” and “Mama I’m Coming Home” while sitting in a black, throne-like chair with a bat on top.
