Jack Osbourne has welcomed a new baby girl into his family — and she has a very familiar name.

Ozzy Matilda Osbourne was born March 5 to Jack and his wife Aree, the couple announced Wednesday (March 11) in a joint Instagram post along with grandma Sharon Osbourne. “Introducing Ozzy Matilda Osbourne,” the caption reads with a short video of the baby girl. The clip includes a “Hello World” card with all of baby Ozzy’s vital stats, including her full name, birth date and time (7:49 a.m.) and her weight (7 pounds, 12 ounces) and length (19 inches).

The birth of Ozzy Matilda comes nearly eight months after the loss of her grandpa Ozzy Osbourne, who died of a heart attack in July 2025 at age 76. His death came weeks after the Back to the Beginning concert in Birmingham, England, which was billed as the rocker’s final concert with his band Black Sabbath. The charity concert raised more than $11 million for Acorns Children’s Hospice, Birmingham Children’s Hospital, and Cure Parkinson’s.

Ozzy Matilda Osbourne is Jack’s fifth child, joining Pearl, Andy and Minnie from his first marriage to Lisa Stelly and Maple with Aree.
