Ozzy Osbourne is a lot of things. Rock legend. Prince of Darkness. Reality TV pioneer. But honestly? If you ask him, he’d probably tell you his most chaotic—and rewarding—role has been "Papa." The Osbourne family tree is famously tangled, stretching across two marriages and decades of life in the spotlight. Because his family is so spread out between the UK and the States, fans are often left scratching their heads: how many grandchildren does Ozzy Osbourne have exactly?
As of early 2026, the count stands at 11.
Wait, did you think it was ten? That’s the most common mistake. People tend to forget about the "hidden" side of the family from Ozzy’s first marriage. While Jack and Kelly’s kids get all the headlines, Ozzy’s eldest children, Jessica and Louis, have been quietly raising their own families for years.
The Breakdown: Counting the Osbourne Grandkids
To really understand the numbers, you have to split the family into two halves. You’ve got the Sharon era and the Thelma Riley era.
Ozzy’s first marriage to Thelma Riley in the 1970s resulted in two biological children, Jessica and Louis. He also adopted Thelma’s son, Elliot, though Elliot doesn’t have children of his own in the public record. From this side of the family, Ozzy has five grandchildren. Jessica has three—Isabelle, Harry, and Kitty. Louis has two—Maia and Elijah.

Then you have the "MTV Osbournes." Jack has been the busiest of the bunch. He currently has four daughters. His sisters, Kelly and Aimee, bring different energies to the table. Aimee has always been fiercely private and hasn't publicly shared news of any children. Kelly, however, welcomed her son Sidney in late 2022.
But here is the detail that catches most people off guard: Jack and his wife, Aree Gearhart, just expanded the tribe again. With their newest arrival in December 2025, the total officially hit 11.
Jack Osbourne’s "Girl Squad" and the Newest Addition
Jack has basically spent the last decade surrounded by pink. He’s a total girl dad. From his first marriage to Lisa Stelly, he has Pearl, Andy Rose, and Minnie. Pearl is the oldest—she’s actually a teenager now, which feels wild if you remember her as a toddler on Ozzy & Jack’s World Detour.
Jack’s second marriage to Aree Gearhart brought Maple Artemis into the world in 2022. Then, in late 2025, the couple welcomed their second child together (Jack's fifth). It’s a full house.

- Pearl Clementine (13): The first of the "Sharon era" grandkids.
- Andy Rose (10): Known for her "lemon face" and being Ozzy's partner in crime.
- Minnie Theodora (7): The youngest from Jack's first marriage.
- Maple Artemis (3): The first child with Aree.
- The 2025 Baby: The newest member of the crew who tipped the count to 11.
Kelly Osbourne and the Mini-Slipknot Legacy
Kelly’s journey to motherhood was a bit more of a whirlwind. She’s with Sid Wilson from the band Slipknot. Their son, Sidney, was born in November 2022.
If you’ve seen the photos, Sidney looks exactly like a tiny version of his grandpa. Kelly has talked openly about how Sidney and Ozzy became "best friends" in Ozzy’s final years. They’d spend every night watching cartoons together. It’s a pretty sweet image: the guy who bit the head off a bat snuggling with a toddler watching Bluey.
The "Secret" Grandkids in the UK
Most casual fans don't realize Jessica and Louis Osbourne even exist because they weren't on the MTV show. Jessica was the one who made Ozzy a grandfather for the very first time.
It happened during the filming of The Osbournes. There’s a scene where Jessica calls to say she’s in labor with Isabelle. Ozzy’s reaction? "Don’t f***ing say that to me!" He wasn't ready to be "Grandpa" yet. But he grew into it.

Jessica’s kids (Isabelle, Harry, and Kitty) and Louis’s kids (Maia and Elijah) mostly live in England. They lead normal, non-celebrity lives. Louis has said in interviews that Ozzy was a "doting grandad" who would call every Sunday just to check in.
Why the Number Matters for the Osbourne Legacy
Sadly, the family had to say goodbye to the patriarch in July 2025. When Ozzy passed away, he left behind a massive, complicated, and incredibly loyal legacy.
Thirteen years ago, when Jack was diagnosed with MS, or when Ozzy was battling Parkinson’s, the family tightened their circle. You see it in the way they talk about each other. It’s not just about the fame; it’s about this weird, rock-and-roll tribe that just keeps growing.
The grandkids are the ones keeping the "Prince of Darkness" spirit alive. Whether it's Pearl dressing up like her grandpa for Halloween or Sidney wearing tiny leather jackets, the Osbourne brand isn't going anywhere.
Actionable Takeaways for Fans
If you're trying to keep up with the Osbournes in 2026, here is the best way to stay updated:
- Follow Jack and Aree: They are the most active on social media regarding the grandkids. They share the most "real life" glimpses of the blended family.
- Check out "The Osbournes Podcast": Since Ozzy’s passing, Sharon, Kelly, and Jack have used the podcast to share memories and updates on how the youngest generation is doing.
- Respect the Privacy of the UK Side: Remember that Jessica and Louis chose to stay out of the limelight for a reason. You won't find much on them, and that's intentional.
Watching the Osbournes go from the wildest family on television to a massive group of 11 grandkids has been one of the most interesting arcs in pop culture history. It’s proof that no matter how much "Iron Man" you have in your soul, you eventually trade the stage lights for bedtime stories.
