Jack Osbourne welcomes new baby named after Ozzy

Jack Osbourne is paying tribute to his late father by naming his new baby after the Prince of Darkness.

The “Osbournes” personality took to Instagram on Wednesday to announce the arrival of baby Ozzy Matilda Osbourne with a brief black-and-white clip of the baby sleeping in what appeared to be a hospital bassinet.

A small printed card near the infant’s head read “Hello, World,” and revealed the birth date as March 5, 2026.

Jack’s baby was born at 8:49 a.m., weighing in at a healthy 7 pounds, 12 ounces and stretching out to all of 19 inches.

A plush bat toy also rested near little Ozzy — a reference to the Black Sabbath rocker’s infamous onstage incident in 1982, in which he bit the head off a live bat.

Jack didn’t state whether his newest addition is a boy or a girl. A rep for Jack did not immediately return Page Six’s request for further details on the new arrival.

Baby Ozzy Matilda, now barely a week old, joins Jack’s four older children — daughters Pearl Clementine, 13, Andy Rose, 10, Minnie Theodora, 8, whom he shares with ex-wife, Lisa Stelly, and Maple Artemis, 3, whom he shares with current wife, Aree Gearhart.

The couple wed back in September 2023.

In December, Jack revealed Aree’s pregnancy during an interview with the Sun — and noted that they were able to share the news with Ozzy prior to his death in July at age 76.

“I think it’s been partly a healthy distraction, partly healing — probably in that kind of ‘full cycle’ category, in a weird way,” Jack told the outlet at the time.

He added, “It’s very much taken energy out of the grieving side of things and parked in a bit more hopefulness.”

Jack, 40, also divulged that he and his wife, 34, were “super excited” about the impending arrival.

“It’s definitely something that we were wanting to pursue and somehow it happened, miraculously,” he explained.

On last Wednesday’s episode of the “Hate to Break it to Ya” podcast, Jack confessed that despite battling Parkinson’s disease and other ailments, Ozzy’s death “was a surprise, for sure.”

“Obviously everyone knew he was sick,” he said. “But we weren’t expecting it to be as quick as it was. I think he was done.” He also shared that Ozzy’s final hours on July 22 weren’t “dramatic.”

“He was up, he was doing his thing, had some breakfast, and that was it,” Jack shared.
