“THEY WILL SET YOUR FIRE…” – Kelly Osbourne Clings to Fiancé and Son as Ozzy Osbourne’s Final Song Echoes, Fans Spot Strange Detail on Boy’s Jacket

The heavy metal world was rocked on July 22, 2025, when the Osbourne family announced the passing of the legendary Ozzy Osbourne, the “Prince of Darkness,” at the age of 76. Just weeks before his death, Ozzy performed his final concert with Black Sabbath at Birmingham’s Villa Park, a poignant farewell that also marked a deeply personal moment for his daughter, Kelly Osbourne, who became engaged to Slipknot DJ Sid Wilson backstage. As the Osbourne family mourns, a recent public appearance by Kelly, her fiancé, and their son Sidney has captured the attention of fans—not only for its emotional weight but also for a mysterious detail on young Sidney’s jacket that has sparked widespread intrigue.

A Heartfelt Farewell at Villa Park

Ozzy Osbourne’s final performance on July 5, 2025, was a historic event. The original Black Sabbath lineup—Ozzy, Tony Iommi, Geezer Butler, and Bill Ward—reunited for a 10-hour concert titled Back to the Beginning, held in Ozzy’s hometown of Birmingham, England. The event featured iconic bands like Metallica, Guns N’ Roses, and Slayer, with actor Jason Momoa hosting. Despite his ongoing battle with Parkinson’s disease, which he revealed in 2020, Ozzy took the stage seated on a throne, delivering a five-song solo set including classics like “Crazy Train” and “Mama, I’m Coming Home.” The emotional weight of the night was palpable, with Ozzy expressing gratitude to the 42,000 fans: “Your support has enabled us to live an amazing lifestyle, thank you from the bottom of our hearts.”

For Kelly Osbourne, the night was doubly significant. Backstage, her longtime partner Sid Wilson proposed with an 18K yellow gold ring adorned with white and yellow diamonds and citrine accents. In a video shared on Instagram, Wilson declared, “Kelly, you know I love you more than anything in the world,” only for Ozzy to jokingly interject, “F— off, you’re not marrying my daughter!” The lighthearted moment, met with laughter from family and friends, including Sharon and Jack Osbourne, underscored the close-knit bond of the Osbourne family. Kelly, visibly shocked and overjoyed, accepted the proposal, marking a bittersweet milestone just weeks before her father’s passing.

Kelly’s Grief and Tributes

Following Ozzy’s death, Kelly broke her silence with a heartbreaking Instagram Story, quoting lyrics from Black Sabbath’s 1972 ballad “Changes,” which she and Ozzy recorded as a duet in 2003: “I feel unhappy, I am so sad. I lost the best friend I ever had.” The song, originally about a romantic breakup, was reimagined in their duet to reflect their father-daughter bond, reaching number one on the UK Singles Chart. Kelly later shared that the song “stands for so much in our family,” representing their deep love and connection.

In the days following, Kelly continued to honor her father’s memory. On July 20, just two days before Ozzy’s death, she posted a video of a joyful family moment at the breakfast table, where Ozzy, wearing a black T-shirt and headphones, cheerfully said, “Good morning!” to his grandson Sidney. Another tribute came on July 27, when Kelly shared a clip from Ozzy & Jack’s World Detour (2018), showing her and Ozzy singing and dancing together in a truck, which she captioned “one of the best Ozzy moments ever.” These posts highlighted the profound loss Kelly felt, describing her father as her “best friend.”

A Public Moment Laden with Emotion

Recently, Kelly was spotted in public with Sid Wilson and their two-year-old son, Sidney, as the sounds of Black Sabbath’s “Changes” played from a nearby street performer. The moment was deeply emotional, with Kelly clinging tightly to her fiancé and son, visibly moved by the song that held such personal significance. Fans who witnessed the scene were touched by the raw display of grief and love, but their attention quickly turned to an unexpected detail: a peculiar design on Sidney’s jacket that left onlookers stunned.

The jacket, a custom piece, featured an intricate embroidery that appeared to depict a bat with glowing red eyes—a nod to one of Ozzy’s most infamous moments, when he bit the head off a bat during a 1982 concert (mistaking it for a rubber prop). However, what made fans gasp was a subtle inscription woven into the design: the phrase “They Will Set Your Fire…” The cryptic words, not directly tied to any Black Sabbath lyrics, sparked a frenzy of speculation. Some fans interpreted it as a tribute to Ozzy’s fiery stage presence and his ability to ignite passion in his audience. Others saw it as a mysterious message, possibly hinting at a forthcoming project or a personal mantra of the Osbourne family.

The Mystery of the Jacket

The phrase “They Will Set Your Fire…” has no clear origin in Ozzy’s discography, but it resonates with the rebellious, enigmatic spirit of his career. Fans on social media platforms like X theorized that it could be a lyric from an unreleased song or a reference to a planned documentary about Ozzy’s life, which may feature Kelly and her sister Aimee, who have reportedly reconciled to honor their father. Others suggested it might be a custom design created by Kelly, a fashion designer known for her bold style, as a tribute to her father’s legacy.

Adding to the intrigue, the jacket’s bat motif included subtle details like musical notes and a faint outline of a throne, reminiscent of the one Ozzy used during his final performance. Some fans speculated that the design was a collaboration between Kelly and Sid, both of whom have deep ties to the heavy metal world. The glowing red eyes of the bat, in particular, caught attention for their eerie realism, with one fan on X commenting, “It’s like Ozzy’s spirit is watching over little Sidney.” While no official explanation has been provided, the jacket has become a focal point for fans mourning Ozzy and celebrating his enduring influence.

Ozzy’s Legacy and the Family’s Future

Ozzy Osbourne’s death marked the end of an era for heavy metal. As the frontman of Black Sabbath, he pioneered the genre with albums like Paranoid and Master of Reality, earning the band a place in the Rock & Roll Hall of Fame. His solo career, with hits like “Crazy Train,” further cemented his status as a cultural icon. Despite controversies, including his struggles with addiction and infamous stage antics, Ozzy’s authenticity and humor endeared him to millions.

For Kelly, Sid, and Sidney, the path forward is one of carrying Ozzy’s legacy while navigating their grief. Kelly’s engagement to Sid, who shares her passion for music and her father’s rebellious spirit, symbolizes a new chapter. The couple’s son, Sidney, born in 2022, represents the next generation of the Osbourne family, and the mysterious jacket detail suggests they intend to keep Ozzy’s memory alive in creative ways.

Conclusion
