Kelly Osbourne and Sid Wilson are engaged!

The Slipknot rocker, 48, proposed to the former Fashion Police host, 40, during her dad Ozzy Osbourne’s final concert with Black Sabbath at England’s Villa Park on Saturday, July 5.

In a video of the moment shared on Instagram, Wilson can be seen grabbing his future bride’s attention, telling her, “Kelly, you know I love you more than anything in the world,” before Ozzy, 76, interjects, “F— off, you’re not marrying my daughter.”

Laughing off the rocker’s comment, Wilson continued, telling Kelly, “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?”

Looking around in shock, Kelly then nodded her head yes, before embracing Wilson in a long hug, as friends and family — including mom Sharon Osbourne and brother Jack Osbourne — cheered them on.

Kelly and Wilson first met and struck up a friendship in 1999, when Wilson’s band was touring with Ozzfest, the music festival founded by her parents.

They officially began dating in January 2022. A source told PEOPLE at the time that they were “very happy together.”

Kelly later reflected on their long history in an Instagram post celebrating their first Valentine’s Day as a couple. “After 23 years of friendship I can’t believe where we have ended up!” she wrote at the time, sharing a photo of the pair kissing. “You are my best friend, my soulmate and I am so deeply in love with you Sidney George Wilson.”

Wilson also shared the love, reposting the photo on his own Instagram page with the message, “There is not enough colours to display the palette of Love I have for you in my Heart 💜 Happy Valentines Day my Love XoXo.”

In May of that same year, the duo shared the big news that they had a baby on the way. Kelly made her pregnancy reveal by posting a photo of herself holding an ultrasound image.

“I know that I have been very quiet these past few months so I thought I would share with you all as to why… I am over the moon to announce that I am going to be a Mumma,” she wrote on Instagram at the time. “To say that I am happy does not quite cut it. I am ecstatic! 🤰💜.”

Their son made his arrival at the end of 2022, and while Kelly had hoped to keep his birth a secret for a while, Sharon, 72 — a very excited grandmother — spilled the beans during a January 2023 appearance on The Talk.

“[His name is] Sidney. [They’re] doing so great. She won’t let a picture go out of him,” she said at the time.

Later that same day, Kelly posted a message on her Instagram Stories, reiterating her desire for privacy. “I am not ready to share him with the world,” she wrote.

During a September 2023 episode of The Osbournes podcast, Kelly opened up about having “fully embraced mom life” and how much she and Wilson adore Sidney.

“He’s the best thing that ever happened to me. The best, he’s lovely,” she said of their son. “I just love being a mom. It is everything to me.”
