Family is forever! Kelly Osbourne is known for being the daughter of legendary musician Ozzy Osbourne and his wife, music manager Sharon Osbourne — but the starlet isn’t the only child the famous rocker couple share together. The couple are also parents to Jack Osbourne and Aimee Osbourne. Plus, the Osbournes alum has two half-siblings from her dad’s previous marriage. Here’s what we know about Kelly’s siblings.

Brother: Jack Osbourne

You probably know Jack, Kelly’s younger bro, from his unforgettable turn on the family’s MTV reality series The Osbournes. The now-fitness and travel reporter started off his career in music, like his mother and father before him. He A&R scouted for Epic Records before starring in the family’s show.

The Osbournes brought Jack a lot of recognition and he went on to do small movie parts and commercials due to the exposure. He had a guest-starring role in Dawson’s Creek in season 6. Sometime later, he starred in his own series, Jack Osbourne: Adrenaline Junkie, after pivoting to fitness shows with Celebrity Wrestling: Bring It On! and Extreme Celebrity Detox.

Jack appeared alongside his dad in History Channel’s Ozzy & Jack’s World Detour, which ended in 2018 after 3 seasons. His most recent starring role is on Portals to Hell, a paranormal research reality series on the Travel Channel.

Sister: Aimee Osbourne

Aimee is Kelly’s older sister — and you wouldn’t remember her from the MTV series. The musician declined to appear on the show for fear it would affect her music career.

She also pursued acting when she was younger. In 2003, she appeared in the MTV adaptation of Wuthering Heights. In 2010, she started making music under the name ARO (her initials) and formed a band. They’ve only played 3 shows at the time of publication.


In July 2020, ARO released their first single in four years, “Shared Something With the Night,” and announced their upcoming debut album Vacare Adamaré.

Half-Brother: Louis John Osbourne

Louis is Ozzy’s son from his first marriage to Thelma Riley in 1971. Years later, the musician referred to this marriage as a “terrible mistake” in his 2010 memoir, I Am Ozzy. In the 2011 documentary film God Bless Ozzy Osbourne, the Black Sabbath alum explained that his touring schedule and frequent drug use took a toll on his parenting, so much so he didn’t remember Louis or daughter Jessica’s birthdays.

Half-Sister: Jessica Hobbs

Jessica is Ozzy’s daughter from his first marriage in 1971.

Adopted Brother: Elliot Kingsley

Ozzy adopted then-wife Thelma’s 5-year-old son, Elliot, when they married.

Adopted Brother: Robert Marcato

Ozzy and Sharon took Robert in after his mother died but never officially adopted him.
