Jack shares 15-month-old Maple with his wife, Aree Gearhart
Step aside Black Sabbath aficionados, Ozzy Osbourne has a new No. 1 fan.
She repeatedly called his name, “Papa,” over and over while pointing at the TV any time Ozzy appeared on screen. Jack, 37, sat on a couch behind his daughter and looked on lovingly as his father performed and Maple made the show her own private party.
“Maple thinks she’s getting a private performance from Papa,” Jack captioned the sweet video.

"I’m hearing our little Maple has gone viral!" she wrote in the caption as she shared the adorable video of her granddaughter. "Who put Papa in the magic box 📺 😂."
Ozzy is father to Jack, Aimee and Kelly Osbourne, who he shares with wife Sharon, 71, as well as Elliot, Louis and Jessica, who he shares with his first wife, Thelma Riley.
The rocker and Sharon, who have been married for over 40 years, are grandparents of five, including Jack’s daughter Maple, as well as his three kids from a previous marriage — Pearl Clementine, Andy Rose, and Minnie Theodora — and Kelly’s son, Sidney, whom she welcomed with boyfriend Sid Wilson at the end of 2022.
From Ozzy’s previous marriage to Riley, he is also grandfather to his son Louis' kids, Elijah and Maia, as well as his daughter Jessica's three kids, Isabelle, Harry and Kitty.
Speaking candidly about his ever-growing family on Sirius XM last year, Ozzy said, "I also have 11 dogs and they all sleep on my bed.”
He added, "It's f---ing crazy in my house."
As for Jack, who starred in season 2 of Fox’s Special Forces: World's Toughest Test, he has a playful relationship with his four daughters.
Speaking to PEOPLE about how he expected his 10-year-old daughter, Pearl, to react to his involvement on the show, he said, "She just thinks it's funny at that kind of, everything's funny and makes fun of everything kind of age right now.”
He added, "I'm excited for her to see it. I'm also dreadfully embarrassed.”
Jack admitted that he doesn’t think his kids will hold the show against him — "I think they're going to just laugh," he said — but his parents had a very different response to his involvement.
"They didn't really get it," he said of initially telling his family about the show. "They kind of get it, but they hadn't seen the show. So their whole thing is just be careful, don't get hurt. You've got kids."
