Kelly Osbourne got engaged to Sid Wilson at her father Ozzy Osbourne’s Black Sabbath farewell concert.

The TV personality took to Instagram Sunday to share a sweet clip of the proposal, which occurred the night before backstage at Villa Park in Birmingham, England.

While surrounded by their family and friends, the Slipknot member said, “Kelly, you know I love you more than anything in the world.”

Ozzy, 76, then jokingly interrupted, saying, “F–k off, you’re not marrying my daughter.”

Laughter erupted from the room, including from Kelly, 40, and her mom, Sharon Osbourne, 76, who was sitting next to her husband.

“Nothing would make me happier than to spend the rest of my life with you,” Wilson, 48, continued.

“So in front of your family and all of our friends, Kelly, will you marry me?” the keyboardist added.

Kelly looked around the room in shock, nodding, “Yes.”

Wilson then slipped the ring on her finger before they hugged.

“Oh and this happened yesterday!” she captioned the post on Instagram.

Kelly and Wilson became friends in 1999 when the latter’s band toured on her parents’ music festival, Ozzfest, per People.

The couple took their relationship to the next level in January 2022 and hard-launched their romance the following month.

“After 23 years of friendship, I can’t believe where we have ended up!” the “Fashion Police” alum wrote via Instagram at the time.

“You are my best friend, my soulmate and I am so deeply in love with you Sidney George Wilson.”

Kelly and Wilson share a 2-year-old son, Sidney, whom they welcomed in November 2022.
