Jack Osbourne has shared an adorable new picture of his four-month-old daughter, and she's taking after her late grandfather in more than just her name!
The young girl, Ozzy Matilda, had a very cheeky smile in the picture, which showed Jack, the youngest son of Ozzy and wife Sharon Osbourne, holding his daughter in his arms while he sat cross-legged in a park.
A mischievous sparkle
"Little miss ozz already has a mischievous sparkle," the 40-year-old father captioned the post, highlighting her smile and recognizing how she has taken after the late rock star.
Her late grandfather Ozzy was the legendary Black Sabbath frontman, who died at age 76 in July 2025. Ozzy was known for his silly sense of humor and goofy mannerisms – at odds with his dark stage persona – and in later years, his bewilderment with the modern world.

Ozzy was dad to three children with Sharon: eldest daughter Aimee, daughter Kelly, 42, and Jack. He also had three children with his first wife, Thelma: Elliot, Jessica, and Louis.
He had 10 grandchildren at the time of his passing: four from Jack, two from Louis, three from Jessica, and grandson Sid from Kelly.
Grandpa Ozzy

"What can I do about it? Grandpa Ozzy, I’m called. But you know what? It happens to everybody eventually if we [have] kids," he told Howard Stern.

The series was one of the first successful reality shows, and turned Kelly, Jack, and Sharon into stars, as well as catapulting Ozzy back into the spotlight after his heyday in the 1970s and 1980s.
Lessons in parenting

"I think so much of parenting is you learn from your parents' mistakes ultimately, and you pick and choose. 'Hey, I liked that my parents did that,' 'I didn't like that my parents did that.' And that's okay, because our parents did the same [expletive]," he admitted on the Leave No Doubt Fatherhood podcast.
"My dad didn't raise me at all like his dad raised him. And same with my mother — she was very different from her parents. And that's kind of, whether people realize it or not, I think that's the gift we give our kids. If they're aware enough, we give them that playbook to operate from when they're ready to be parents.
