The Prince of Darkness made a surprise posthumous appearance on the finale of Lego Masters Jr. Kelly Osbourne has been one of the hosts of the Fox reality competition spinoff since its debut in August 2025. This week’s episode of the competition series had a message from Ozzy himself.
In a TikTok video shared by Reality Club FOX, Kelly asks for some help from her father, who appears remotely via video. Needing to scare the kid contestants on the time restraints, Ozzy answered with “I’d love to” while manically cackling and running his hands together.
“One hour left, kids. You’ve got one hour left to finish those builds — or else!” said the legendary rocker as the lights flashed red and a heavy guitar riff played.
Kelly sent him off saying, “Thank you, Daddy. That was perfect. We love you.”
Some of the young contestants seemed to have no idea who the infamous metal rocker was, with one young girl saying that her father loves Ozzy.
@realityclubfox What an honor it was to have the prince of darkness make a cameo on LEGOMastersJR. 🖤 #OzzyOsbourne #KellyOsbourne
Fans couldn’t help but be baffled at the fact that many of the contestants asked, “Who is that?” when Ozzy appeared on screen. But they also shared their sentiment of being able to see Ozzy again since his death.
“I was not prepared to ball during the final show. Then boom Ozzy (and I didn’t want it to end),” said one comment.
Another said, “Best part, he was having a blast and I know he was supportive of them.”
“That honestly sounds awesome getting scared by the king of darkness himself,” added one fan.
Ozzy appeared during the final challenge of the finale episode, where the contestants were tasked with building a Ninjago Lego set of a dragon with special effects. Instead of Will Arnett marking the one-hour countdown, it was Ozzy’s honor.
The metal rocker died on July 22 at the age of 76 after suffering a heart attack and health issues related to his Parkinson’s. He had recently held his last concert in Birmingham before his death. A documentary about Ozzy, titled Back to the Beginning: Ozzy’s Last Bow, will be released in theaters next year.
